WASHINGTON — The congressional power to remove a president from part through impeachment is the ultimate check on the chief executive. No president has e'er been forced from the White House that manner, although Richard Nixon resigned rather than having to face up the most certainty that he would exist removed from part.

Congress derives the say-so from the Constitution. The term "impeachment" is usually used to mean removing someone from office, only it really refers simply to the filing of formal charges. If the House impeaches, the Senate then holds a trial on those charges to decide whether the officer — a president or any other federal official — should be removed and barred from belongings federal office in the hereafter.

The House has impeached xix people, more often than not federal judges. Two presidents, Andrew Johnson and Bill Clinton, were impeached, only the Senate voted not to convict either of them. Nixon resigned after the Judiciary Committee approved three articles of impeachment but earlier the full House voted on them.

The Constitution provides that a president can exist impeached for "treason, bribery, or other high crimes and misdemeanors." Treason and bribery are well understood, but the Constitution does not define "high crimes and misdemeanors."

Congress has identified three types of deport that constitute grounds for impeachment, including misusing an part for financial gain. But the misdeeds need not exist crimes. A president can be impeached for abusing the powers of the role or for acting in a manner considered incompatible with the function.

When Gerald Ford was a member of the House, he defined an impeachable offense equally "whatever a bulk of the House of Representatives considers it to be at a given moment in history." In other words, impeachment and conviction by Congress is a political penalization, not a criminal 1.

1. What constitutes an impeachable offense?

The founders intentionally kept the term "high crimes and misdemeanors" vague, because impeachment is meant to be a political human activity, non a legal i. Different in criminal police force, there are no clear rules for evaluating when a president has stepped over the ramble line.

The founders rejected the term "maladministration" every bit grounds for impeachment. They didn't desire a president tossed out simply considering Congress didn't recollect he was doing a good job. Alexander Hamilton said impeachable offenses were those that involved abuse of public trust. The term is more often than not understood to hateful corruption of office that results in harm to the public.

The House impeached Andrew Johnson in 1868 during a fight over reconstruction afterward the Ceremonious War. Most of the articles of impeachment defendant him of violating a federal law, since repealed, that said a president could not remove certain officials without Senate approval.

The Business firm Judiciary Committee approved three articles of impeachment against Nixon in 1974, charging him with:

  • Obstruction of justice, for impeding the investigation into the break-in at Democratic National Committee headquarters in the Watergate office edifice;
  • Corruption of power, for trying to employ the CIA, FBI and other agencies to cover up the Watergate conspiracy; and
  • Antipathy of Congress, for refusing to turn over cloth in response to congressional subpoenas.

The House canonical 2 articles of impeachment confronting President Neb Clinton in 1998, charging him with:

  • Lying under adjuration to a grand jury about the nature of his relationships with Monica Lewinsky and Paula Jones; and
  • Obstruction of justice, for encouraging Lewinsky and others to make fake statements and concealing gifts he had given her.

ii. How is the Trump investigation unlike from what happened with Clinton?

Iii committees in the House — Intelligence, Oversight and Foreign Diplomacy — are conducting investigations, gathering documents and calling witnesses in the research into Trump. In the Clinton impeachment, one committee, the House Judiciary, relied heavily on a report compiled by Kenneth Starr, the independent counsel who led the investigation, that listed 11 possible grounds for impeachment in four categories — perjury, obstruction of justice, witness tampering and abuse of ability.

House Speaker Nancy Pelosi, D-Calif., has said that while the Intelligence Committee will accept the lead in investigating Trump, the actual vote on specific manufactures of impeachment will be conducted by the Judiciary Committee and could draw on the conclusions of other House committees, as well, though that seems unlikely. The procedure of voting on the articles, known as the committee marker-upward, will exist televised and will likely take identify over several days.

Business firm Judiciary took six days to recommend manufactures of impeachment against Nixon in July 1974 and 3 days to recommend articles of impeachment against Clinton in December 1998.

If approved by a simple majority, the articles are reported to the full House and are privileged, meaning they can come upwards for immediate consideration, including potentially several days of argue. The president is impeached if the Business firm approves any of the articles of impeachment by a simple majority vote. The Business firm then appoints members to serve as "managers," or prosecutors, for the Senate trial.

3. Must the House pass a resolution to officially launch an impeachment investigation?

The Constitution imposes no such requirement, and House rules don't either, even though authorizing resolutions were passed in each of the three previous presidential impeachments.

Rep. Peter Rodino, D-North.J., who was chairman of House Judiciary in 1974 during the Nixon case, chosen passing a resolution "a necessary step." House rules does not place jurisdiction over impeachment in any specific committee, and Rodino said that in past impeachments the Firm had passed a resolution to give the investigating committee subpoena power. But the current Firm leadership has said that such a resolution isn't needed, because the relevant committees already have the necessary subpoena and staffing authority.

White House counsel Pat Cipollone is right in saying that the Firm "has never attempted to launch an impeachment inquiry confronting the president without a bulk of the House taking political accountability for that decision" by passing a resolution.

Merely such a vote is not required. The House has voted to impeach federal judges without passing a resolution to authorize an investigation, and the House procedure for impeaching judges and presidents is the same. Fifty-fifty so, Business firm Democrats will hold a vote Thursday to clarify the rules for public hearings, even though a federal judge said on October. 25 that "a Business firm resolution has never, in fact, been required to begin an impeachment enquiry."

4. Would passing a resolution give Congress authorisation to get g jury material, such as show gathered during the Robert Mueller investigation?

Not necessarily. A fight over this issue is at present in federal court, and the Firm won the first round.

The House leans on what happened in 1974. After a federal grand jury in Washington finished an investigation of the Watergate scandal, it prepared a special report on its findings and recommended that its work be forwarded to the Business firm Judiciary Committee, which had begun impeachment proceedings.

Judge John Sirica ruled that while the m jury's piece of work was surreptitious, he had the authority to release the fabric to the Firm. He said that the normal reasons for keeping grand jury proceedings undercover — such as preventing the escape of someone who might be indicted or insulating the grand jury from outside influence — no longer applied once the one thousand jury'southward work was done. And he noted that Nixon did not object to letting the House committee get the textile. That'southward an of import fact.

A federal appeals court agreed with Sirica's decision, and the grand jury material was turned over to the Business firm.

Since and so, the federal courts have narrowed the ability of judges to declare exceptions to chiliad jury secrecy. Earlier this year, for example, the D.C. Circuit Court of Appeals said in a different example that there's no exception assuasive historians to get access. The courtroom said it interpreted what Sirica did in Watergate every bit immune under a federal dominion that allows giving yard jury textile to the House for "judicial proceedings." Only that was said in a footnote: It was not the holding in the example, and that comment did not make any new police force.

The Justice Department's view is that the issue isn't settled. It said in a recent filing in the electric current lawsuit that no court has ever squarely decided whether a House impeachment proceeding qualifies every bit an exception to longstanding rules of m jury secrecy. And if Trump — dissimilar Nixon — explicitly objects to turning the material over, that could exist a decisive factor.

In tardily Oct, Federal District Courtroom Judge Beryl Howell ordered the Justice Department to give the House Judiciary Committee an unredacted version of the Mueller study, along with some underlying materials. She concluded that the requirement for preserving one thousand jury secrecy was outweighed by the House Judiciary Committee's need for the material in its impeachment investigation. The Justice Department immediately appealed.

5. Practice the president's lawyers get to participate in the House impeachment hearings?

This point is sometimes misunderstood. After the White House counsel complained that no Trump lawyers have been allowed to take part in the Firm committee sessions, many commentators said that the criticism was misplaced, because Trump'due south lawyers would get their gamble in the Senate trial, not in the House proceeding. But that's not how information technology has worked earlier.

In both the Nixon and Clinton proceedings, lawyers for the president were involved in the Firm impeachment process. In 1974, the Judiciary Committee gave Nixon's lawyers copies of documents and testify, immune them to sit in on all hearings, including those in executive session, and permitted them to question witnesses who testified before the committee. Clinton'southward lawyers were likewise immune to present witnesses and to briefly question Starr, the independent counsel whose written report formed the courage of the case for impeachment.

In the current proceedings, the Firm Judiciary Committee recently adopted a rule allowing the president's lawyers to respond to bear witness and testimony in writing. But there is no requirement for such an adaptation to the president's lawyers, and in that location was no such arrangement when the House impeached Andrew Johnson.

6. Must the Senate concord a trial, or can it simply sit on the House articles of impeachment?

The Constitution simply says the Senate has "the sole power to endeavour all impeachments," and some scholars have suggested this means the Senate is empowered but non required to carry out this function. Only Senate rules suggest that information technology's a duty, non an option. Note the word "shall" in Senate Impeachment Rule 1:

"Whensoever the Senate shall receive observe from the Business firm of Representatives that managers are appointed on their office to acquit an impeachment against any person and are directed to deport articles of impeachment to the Senate, the Secretarial assistant of the Senate shall immediately inform the House of Representatives that the Senate is ready to receive the managers for the purpose of exhibiting such manufactures of impeachment, agreeably to such find."

In whatever effect, Senate Majority Leader Mitch McConnell, R-Ky., has said: "Under the impeachment rules of the Senate, nosotros'll have the matter up. ... Nosotros intend to practise our constitutional responsibility."

7. How does a Senate trial work?

The Constitution lays out only 3 requirements: The main justice presides over the Senate trial of a president (just not the trial of any other official); each senator must exist sworn (like to the way jurors take an adjuration); and a 2-thirds vote is required to captive on any article of impeachment.

Once the preliminaries are out of the manner, the trial takes place nether procedures like to courtrooms. The House managers brand an opening argument, followed by a statement from lawyers for the president.

During impeachments of judges, the evidence is generally presented during committee hearings at which the House managers call their witnesses, who tin can be cross-examined. And and then the reverse happens, with the president's counsel calling witnesses who can be cross-examined by the Business firm managers. The Senate has yet to make up one's mind whether, if Trump is impeached, witnesses will be allowed to evidence to the total Senate.

There'due south no requirement for the president to appear, and he cannot be compelled to testify.

Like jurors in a trial, senators sit and listen. The rules say if they have questions, they can submit them in writing to be asked past the main justice.

After both sides make their closing arguments, the Senate begins deliberations, traditionally in airtight session. The Senate and then votes separately on each commodity of impeachment, which must take identify in open session.

8. What is the office of the main justice?

It's limited. The Senate has not adopted rules of evidence, but the rules give the chief justice the dominance to decide on all evidentiary questions. He tin can also put the questions to the full Senate for a vote on admissibility. Chief Justice William Rehnquist, who presided over the Clinton impeachment, quoted from Gilbert and Sullivan in responding to a letter inquiring about his time as presiding officer: "I did nothing in item, and I did it very well."

9. Could the president pardon himself if he'south impeached?

No. The same constitutional provision that gives the president the power "to grant reprieves and pardons for offenses confronting the United States" adds this phrase: "except in cases of impeachment."

ten. What would happen if the Senate convicted Trump?

He would exist immediately removed from office, triggering the 25th Subpoena. Vice President Mike Pence would become president.

That would create a vacancy in the office of vice president, then Pence would nominate someone to succeed him, who would become vice president upon confirmation by both houses of Congress.

This is the procedure followed when Nixon resigned. Ford, the vice president, became president and nominated every bit vice president old New York Gov. Nelson Rockefeller, who was confirmed after extensive congressional hearings.
