Impeachment 101

Donald Trump, 45th president 
of the United States.

Donald Trump has joined the company of a small group of presidents now that he is the subject of an official impeachment inquiry in the United States House of Representatives. Only three previous presidents experienced the impeachment process: Andrew Johnson and Bill Clinton, who were found not guilty after trials in the Senate, and Richard Nixon, who resigned to avoid being impeached in the House and removed from office by the United States Senate.

Contrary to common knowledge, impeachment does not mean automatic removal from office. It is a much more complicated, considered process. Rarely used due to its irrevocable nature, impeachment, as defined in the U.S. Constitution, was a critical feature of the government created by the Founding Fathers. The new nation had just freed itself from rule by a tyrannical monarch and wanted nothing remotely similar in its newly created government. 

Impeachment was considered extensively in The Federalist Papers, a collection of essays written in 1788 by John Jay, James Madison, and Alexander Hamilton. These articles urged citizens of New York State to ratify the United States Constitution. They promoted the ideas and plans that had been debated and drafted at the Constitutional Convention the year before. The Federalist Papers is considered one of the most significant American contributions to political discourse and az definitive source for understanding the original intent of the framers of the Constitution.

From the Federalist Papers, written by James Madison, Alexander Hamilton, and John Jay.

In Federalist 51, James Madison argued for a watchdog system between the three branches of government: the legislative, executive, and judicial. Federalist 51 was entitled “The Structure of the Government Must Furnish the Proper Checks and Balances Between the Different Departments.” Madison, a future president, wrote that “If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself.” 

Wikimedia.com James Madison, “If angels were to govern men...

The most practical way to keep the government in check, Madison argued, was to structure it so that politicians must compete with each other. “Ambition must be made to counteract ambition,” he wrote. During the Constitutional Convention, Madison also said about impeachment: “You need it because a president might betray his trust to foreign powers."
Having said that, the Founders did not invent impeachment. The concept had its roots in British common law, and was used beginning in the 14th century. The House of Commons served as prosecutor and the House of Lords as judge in an impeachment proceeding against a government official charged with a criminal offense. Conviction on impeachment could result in fines, imprisonment, and even execution. In the United States, the penalties extend no further than removal and disqualification from office. Possible criminal liabilities, however, remain for an impeached and removed official. 

In the early 1800s, an understanding that cabinet ministers were responsible to Parliament (rather than to the monarch) ended the use of impeachment in Great Britain.
In the United States impeachment has rarely been used, largely because it is so potentially overwhelming to the political system. Impeachment can occupy Congress for a long period of time, involve substantial amounts of testimony, and bring about deep political conflict. 
Attempts to amend the procedure, however, have not worked, partly because impeachment is regarded as a key part of the system of checks and balances in the U.S. government. These rules describe the intricate inter-relatedness of the three branches of government and their powers to hold each other accountable.
Wikimedia.com  Andrew Johnson, 17th president of the United States.
The idea of impeaching and removing a president is the ultimate accountability of high officials to the land they swear a high oath to defend. The actual language on impeachment in the Constitution says that the president, vice-president and all civil officers of the United States "shall be removed from office on impeachment for conviction of treason, robbery or other high crimes and misdemeanors,” terms debated by politicians and historians to this day.

Congressman Gerald Ford, who became president as the result of an impeachment process, notably said that “an impeachable offense is whatever a majority of the House of Representatives considers it to be at a given moment in history.” High crimes and misdemeanors can include obstruction of justice or perjury (lying under oath during a trial or investigation), violating an oath of office, or flouting the emoluments clause of the Constitution. This stricture prohibits members of the government from receiving gifts, offices, or titles from foreign states and monarchies without the consent of the United States Congress.
Previous impeachment proceedings: 2 acquittals, 1 resignation
The nation's experience with presidential impeachment begins with Andrew Johnson, the 17th president, who assumed office after the assassination of Abraham Lincoln in 1865. During the Civil War, Johnson was the only Southern senator to remain loyal to the Union and Lincoln chose him as vice president for his second term. Six weeks after Johnson became vice president, Lincoln was assassinated. As president, Johnson took a moderate approach to restoring the South to the Union, and clashed with congressional Radical Republicans who wanted to ensure congressional rather than presidential control Reconstruction. Congress passed a number of measures to protect Southern blacks over Johnson’s veto. Johnson wanted to quickly restore the Southern states to the Union. He granted amnesty to most former Confederates and allowed the rebel states to elect new governments. These

governments, which often included ex-Confederate officials, soon enacted black codes, measures designed to repress the recently freed slave population. The Radical Republicans viewed Johnson's approach to Reconstruction as too lenient toward the former Confederacy. Hostilities between the president and Congress mounted and in February 1868, the House voted to impeach Johnson. Among the 11 charges, he was accused of violating the Tenure of Office Act by firing the Secretary of War, who opposed Johnson’s Reconstruction policies. At his Senate trial, Johnson was acquitted  by one vote.
Richard Nixon, the 37th president, was elected in 1968 and reelected by a landslide in 1972. He was embroiled in controversy throughout his time in office. During his term, the Vietnam War continued to stir public unrest. A burglary at the Democratic National Committee

was called Watergate (after the location of the Democratic headquarters). 
Investigations beginning in June 1972 eventually revealed a widespread covert, illegal political operation run by the Nixon White House. A deep political and constitutional fight ensued.
In Nixon's case, first Senate hearings and then a Congressional impeachment inquiry deepened the crisis in 1973 and 1974. Nixon’s popularity plunged. When he was revealed on tape to have lied about his early knowledge of the burglary and cover up, Nixon’s fate was sealed. Republican leaders went to the White House to tell Nixon that he could not avoid removal from office. He resigned even before the House had voted on a formal impeachment charge. 
At the point of Nixon's resignation, the Judiciary Committee had approved three articles of impeachment for obstruction of justice, abuse of power, and contempt of Congress.  These  articles were reported to the full House of Representatives.

Clinton faced an impeachment that was generally considered a partisan type of vote. Only Republicans in the House voted affirmatively. In December 1998, Clinton was formally impeached by the House for perjury and obstruction of justice. The charges related to  his testimony denying a sexual relationship with White House intern Monica Lewinsky, testimony given during a deposition for a sexual harassment lawsuit filed by another woman, Paula Jones. In the Senate trial, the perjury charge received forty-five votes, and the obstruction of justice charge received fifty votes, both falling well short of the two-thirds threshold for removal. 


9 essential facts to know about impeachment
There is a step-by-step process for impeaching a president of the United States. It all centers around Article I Sections 2 and 3 of the Constitution and around rules of conduct set by the House of Representatives and the Senate.

One. The House Judiciary Committee is specifically charged by the Constitution to begin the process. When a majority of the committee members vote in favor of what’s called an “inquiry of impeachment” resolution, the process begins.

Two. That initial resolution goes to the full House of Representatives, where a majority has to vote yes, and

The United States Senate in session.

then votes to authorize and fund a full investigation by the 
Judiciary Committee to determine if sufficient grounds exist for impeachment.

Three. The House Judiciary Committee begins hearings. Its investigation can rely on investigations undertaken previously by  the FBI, the Justice Department or a Special Prosecutor.

Four. If a majority of the Judiciary Committee members decides there are sufficient grounds for impeachment, the committee issues a resolution describing specific allegations of misconduct in one or more articles of impeachment.

Five. The entire House then debates that Resolution and votes–on all articles or on each article separately. The House isn’t bound by the Committee’s work. It may vote to impeach even if the Committee doesn’t recommend impeachment.

Six.  If recommending impeachment, Congress then notifies the Senate, which has longstanding rules and procedures for conducting a trial. The House’s formal Resolution of Impeachment becomes in effect the charges for a Senate trial.

Seven. The Senate presents a summons to the president, who is now effectively the defendant, informing him of the charges and the date by which he has to respond.

Eight. The Senate conducts its trial. In that trial, those who are representing the House--that is, the prosecution--and lawyers for the president, both make opening arguments. The case proceeds as a regular court trial, with evidence, witnesses, examination and cross-examination. Uniquely, the trial is presided over by the chief justice of the Supreme Court.
Wikimedia.com
The Senate held hearings on the Watergate investigation in 1973.

The House managers and counsel for the president then make closing arguments. 

Nine. The Senate meets, first in closed session to deliberate, just as a regular jury does.

The Senate then returns in open session to vote on whether to convict the president on the articles of impeachment. Conviction again requires a super majority--not 50 percent but two-thirds of the Senate.

Conviction on just one article of impeachment results in removal from office. Such a conviction also disqualifies the now former president from holding any other public office. Conviction still leaves a former president liable to future legal proceedings and punishment. 

In a notable and disputed exception, President Ford granted a full pardon to his predecessor, Richard Nixon, shortly after his resignation, for any possible criminal acts he may have committed in office.
 
Quotes on Impeachment
 


-Alexander Hamilton, first Secretary of the Treasury and Founding Father.

“The awful discretion, which a court of impeachment must necessarily have, to doom to honor or to infamy, the most confidential and the most distinguished characters of the community, forbids the commitment of the trust to a small number of persons.”











- George McGovern, former U.S. Senator and presidential candidate.




“When people ask if the United States can afford to place on trial the president, if the system can stand impeachment, my answer is, 'Can we stand anything else?'”








 
- Peggy Noonan, former presidential speechwriter



“The Democrats had long labeled the impeachment debate a distraction from the urgent business of a great nation. But the Republicans argued that the pursuit of justice is the business of a great nation. In winning this point, they caught the falling flag, producing a triumph for the rule of law, a reassertion of the belief that no man is above it, and a rebuke for an arrogance that had grown imperial.”









 

- Alexis de Tocqueville, author, Democracy in America








“There are many men of principle in both parties in America, but there is no party of principle.”

Any amount of running linked to significantly lower risk of early death

The brain is at the center of your health. Learn how.


Substantial improvements in population health/longevity

likely if more people took it up, say researchers

November 4, 2019
British Journal of Sports Medicine.
Any amount of running is linked to a significantly lower risk
of death from any cause, finds a pooled analysis
of the available evidence, published online in the
British Journal of Sports Medicine.
If more people took up running -- and they wouldn't have to run far or
fast -- there would likely be substantial improvements in population health and
longevity, conclude the researchers.
It's not clear how good running is for staving off the risk of death from
any cause and particularly from cardiovascular disease and cancer,
say the researchers.

Nor is it clear how much running a person needs to do to reap
these potential benefits, nor whether upping the frequency,
duration, and pace -- in other words, increasing the 'dose' --
might be even more advantageous.

To try and find out, the researchers systematically reviewed relevant
published research, conference presentations, and doctoral theses
and dissertations in a broad range of academic databases.

They looked for studies on the association between running/jogging
and the risk of death from all causes, cardiovascular disease, and cancer.
They found 14 suitable studies, involving 232,149 people,
whose health had been tracked for between 5.5 and 35 years.
During this time, 25,951 of the study participants died.
When the study data were pooled, any amount of running was
associated with a 27% lower risk of death from all causes
for both sexes, compared with no running.
And it was associated with a 30% lower risk of death
from cardiovascular disease, and a 23% lower risk of death from cancer.
Even small 'doses' -- for example, once weekly or less, lasting
less than 50 minutes each time, and at a speed below
6 miles (8 km) an hour, still seemed to be associated
with significant health/longevity benefits.

So running for 25 minutes less than the recommended weekly
duration of vigorous physical activity could reduce the risk of death.
This makes running a potentially good option for those whose main
obstacle to doing enough exercise is lack of time, suggest the researchers.
But upping 'the dose' wasn't associated with a further lowering
of the risk of death from any cause, the analysis showed.
Nevertheless, they suggest that any amount of running is
better than none, concluding: "Increased rates of participation in
running, regardless of its dose, would probably lead to
substantial improvements in population health and longevity."

Stressed to the max? Deep sleep can rewire the anxious brain


Learn how the brain controls stress. 

A sleepless night can trigger up to a 30 percent rise in emotional

stress levels, new study shows

:
November 4, 2019:
University of California - Berkeley
Researchers have found that the type of sleep most apt to calm and reset the anxious brain
is deep sleep, also known as non-rapid eye movement (NREM) slow-wave sleep, a state in
which neural oscillations become highly synchronized, and heart rates and blood pressure drop.

When it comes to managing anxiety disorders, William Shakespeare's
Macbeth had it right when he referred to sleep as the "balm of hurt minds."
While a full night of slumber stabilizes emotions, a sleepless night can trigger
up to a 30% rise in anxiety levels, according to new research from the
University of California, Berkeley.
UC Berkeley researchers have found that the type of sleep most apt to calm and reset
the anxious brain is deep sleep, also known as non-rapid eye movement (NREM) slow-wave
sleep, a state in which neural oscillations become highly synchronized, and heart rates and
blood pressure drop.
"We have identified a new function of deep sleep, one that decreases anxiety overnight
by reorganizing connections in the brain," said study senior author Matthew Walker,
a UC Berkeley professor of neuroscience and psychology. "Deep sleep seems to be a
natural anxiolytic (anxiety inhibitor), so long as we get it each and every night."
The findings, published today, Nov. 4, in the journal Nature Human Behaviour,
provide one of the strongest neural links between sleep and anxiety to date. They
also point to sleep as a natural, non-pharmaceutical remedy for anxiety disorders,
which have been diagnosed in some 40 million American adults and are rising among
children and teens.
"Our study strongly suggests that insufficient sleep amplifies levels of anxiety and,
conversely, that deep sleep helps reduce such stress," said study lead author
Eti Ben Simon, a postdoctoral fellow in the Center for Human Sleep Science at UC Berkeley.
In a series of experiments using functional MRI and polysomnography, among other measures,
Simon and fellow researchers scanned the brains of 18 young adults as they viewed
emotionally stirring video clips after a full night of sleep, and again after a sleepless night.
Anxiety levels were measured following each session via a questionnaire known as the
state-trait anxiety inventory.
After a night of no sleep, brain scans showed a shutdown of the
medial prefrontal cortex, which normally helps keep our anxiety in check,
while the brain's deeper emotional centers were overactive.
"Without sleep, it's almost as if the brain is too heavy on the emotional accelerator
pedal, without enough brake," Walker said.
After a full night of sleep, during which participants' brain waves were
measured via electrodes placed on their heads, the results showed their anxiety
levels declined significantly, especially for those who experienced more slow-wave
NREM sleep.
"Deep sleep had restored the brain's prefrontal mechanism that regulates our emotions,
lowering emotional and physiological reactivity and preventing the escalation of anxiety,"
Simon said.
Beyond gauging the sleep-anxiety connection in the 18 original study participants,
the researchers replicated the results in a study of another 30 participants.

Across all the participants, the results again showed that those who got more
nighttime deep sleep experienced the lowest levels of anxiety the next day.
Moreover, in addition to the lab experiments, the researchers conducted an
online study in which they tracked 280 people of all ages about how both their sleep and
anxiety levels changed over four consecutive days.
The results showed that the amount and quality of sleep the participants got from
one night to the next predicted how anxious they would feel the next day. Even subtle
nightly changes in sleep affected their anxiety levels.
"People with anxiety disorders routinely report having disturbed sleep, but rarely is
sleep improvement considered as a clinical recommendation for lowering anxiety,"
Simon said.


Learn how the brain controls stress. 

"Our study not only establishes a causal connection between sleep and anxiety, but it
identifies the kind of deep NREM sleep we need to calm the overanxious brain."
On a societal level, "the findings suggest that the decimation of
sleep throughout most industrialized nations and the marked escalation in anxiety
disorders in these same countries is perhaps not coincidental, but causally related,"
Walker said. "The best bridge between despair and hope is a good night of sleep."
Co-authors of the study are Aubrey Rossi and Allison Harvey, both at UC Berkeley.

Does sleep boost memory, affect autism, Alzheimer's?

Why do we feel great after a solid night's rest and crummy without one?

Are we "brainwashed" during sleep?
Cerebrospinal fluid washes in and out of brain during sleep

Summary:
A new study illustrates that the brain's cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins from the brain.



FULL STORY
New research from Boston University suggests that tonight while you sleep, something amazing will happen within your brain. Your neurons will go quiet. A few seconds later, blood will flow out of your head. Then, a watery liquid called cerebrospinal fluid (CSF) will flow in, washing through your brain in rhythmic, pulsing waves.

"We've known for a while that there are these electrical waves of activity in the neurons," says study coauthor Laura Lewis, a BU College of Engineering assistant professor of biomedical engineering and a Center for Systems Neuroscience faculty member. "But before now, we didn't realize that there are actually waves in the CSF, too."

This research may also be the first-ever study to take images of CSF during sleep. And Lewis hopes that it will one day lead to insights about a variety of neurological and psychological disorders that are frequently associated with disrupted sleep patterns, including autism and Alzheimer's disease.

The coupling of brain waves with the flow of blood and CSF could provide insights about normal age-related impairments as well. Earlier studies have suggested that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins from the brain. As people age, their brains often generate fewer slow waves. In turn, this could affect the blood flow in the brain and reduce the pulsing of CSF during sleep, leading to a buildup of toxic proteins and a decline in memory abilities. Although researchers have tended to evaluate these processes separately, it now appears that they are very closely linked.
