The law professors wrote, "[i]t goes without saying that lying under oath is a very serious offense. But even if the House of Representatives had the constitutional authority to impeach for any instance of perjury or obstruction of justice, a responsible House would not exercise this awesome power on the facts alleged in this case." The historians wrote, "[t]he Framers explicitly reserved [impeachment] for high crimes and misdemeanors in the exercise of executive power. Impeachment for anything else would, according to James Madison, leave the President to serve 'during the pleasure of the Senate,' thereby mangling the system of checks and balances that is our chief safeguard against abuses of power . . . Although we do not condone President Clinton's private behavior or his subsequent attempts to deceive, the current charges against him depart from what the Framers saw as grounds for impeachment."

[T]he framers were deliberately vague. They didn't want to limit it to treason and bribery because they knew that there were other things that could so violate the basic structure of our constitution, of checks and balances, that they couldn't even predict in advance. So they wanted a general term that would refer to profound abuses of power that threaten the rule of law. Those needn't be crimes. For example, if the president promises to pardon anybody who beats up one of his opponents, or beats up a non-white immigrant, and basically says, "All of you guys have a get out of jail free card." That would be a manifestly impeachable offense, but it wouldn't be a crime. At the same time there are some crimes that are not high crimes and misdemeanors in the sense that the framers used that language, like tax evasion. ...[I]f this president is evading his taxes, that's not an abuse of his official powers. But they resisted going even further and making it a complete free-for-all. That is, at one point they debated making maladministration... impeachable... Well, that could mean any disagreement with the president. There are some countries that say that misconduct is... impeachable... There are some states that, in application to their governor say that misbehavior is... impeachable... Well that would mean that any time the Congress disagrees profoundly with the president on policy... Suppose it passes a law, he vetoes it, they can't override the veto, but if they basically say... we were right and you were wrong, they could just impeach him. ...An effort of that kind was made with President John Tyler. They thought he vetoed too many bills, and that was the impeachable offense. So the framers of the constitution struck a balance and left the judgement to us. They didn't try to create a formula for what was an impeachable offense, but they didn't just say any time you disagree with president, the thing to do is impeach him and try to remove him. They struck a balance in between, and a pretty good one, although it's one that leaves a huge amount of judgement to... we the people.

Other precedents also undermine the House Managers' insistence that the Senate is bound to remove President Clinton from office. The House Judiciary Committee refused on a bipartisan basis to impeach President Nixon for deliberately lying under oath to the Internal Revenue Service, although he under reported his taxable income by at least $796,000. During the 1974 Judiciary Committee debates, many Republican and Democratic members of the Committee agreed that tax fraud was not the kind of abuse of power that impeachment was designed to remedy. Finally, the House Managers argue that President Clinton must be removed to protect the rule of law and cleanse the office. It is not enough, they say, that he can be prosecuted once he leaves office. But protecting the rule of law under the Constitution is not the proper standard for removal of the President. Before impeaching and convicting the President, the Senate must find that he committed 'Treason, Bribery, or other high Crimes and Misdemeanors.' As Professor Laurence Tribe testified before the House Judiciary Subcommittee on the Constitution, '[i]f the proposition is that when the President is a law breaker, has committed any crime, then the rule of law and the take care clause requires that one impeach him, then we have rewritten the [impeachment] clause.'

The President of the United States would be liable to be impeached, tried, and, upon conviction of treason, bribery, or other high crimes or misdemeanors, removed from office; and would afterwards be liable to prosecution and punishment in the ordinary course of law.

The power of impeachment is given by this Constitution, to bring great offenders to punishment. It is calculated to bring them to punishment for crimes which it is not easy to describe, but which every one must be convinced is a high crime and misdemeanor against the government.

The impeachment process was never intended to become a weapon for a partisan majority in Congress to attack the President. To do so is a violation of the fundamental separation of powers doctrine at the heart of the Constitution. It is an invitation to future partisan majorities in future Congresses to use the impeachment power to undermine the President. It could weaken Republican and Democratic Presidents alike for years to come. This case is a constitutional travesty. We deplore the conduct of President Clinton that led to this yearlong distraction for the nation. But we should deplore even more the partisan attempt to abuse the Constitution by misusing the impeachment power.

Abu Ghraib is unbelievable in the innocent times of 1961, that we would torture people that way, and on the instructions of the president of the United States and his highest legal advisers. “Torture is OK,” they said. “Go for it, fellas.” If we can’t renounce that and remove it from office, then the Constitution doesn’t work anymore... We’ve got to do more than take back the Constitution. There has to be accountability for what’s happened. The Constitution says that the president, vice president and other officials of the United States shall be removed from office upon impeachment for and conviction of high crimes and misdemeanors.... If you care about the Constitution, you better start talking to your member of the House of Representatives and say impeachment now is essential to the integrity of the United States government and to the future of the United States. We’ve had more than 500,000 people sign on “Vote to Impeach.” We need to get 5 million, and we need to get 5 million on there quick. And then the Congress will react.

[T]he lesson from the Clinton impeachment is that purely partisan impeachments for offenses like lying under oath about a sexual affair, that don't really shake the Republic and threaten our ability to abide by the rule of law in general; that those kinds of impeachments are going to fail in the Senate and only embolden and empower the acquitted president. So Clinton's popularity just soared after the impeachment was rejected by the Senate. The Andrew Johnson impeachment is rather different. In that one, where he came within one vote of being convicted, most historians have concluded that the impeachment was terribly partisan, that it wasn't based on any real abuse. The basic charge on which he was impeached was his decision to fire the , , without the consent of the Senate, in violation of... the Tenure of Office Act. Now that was a technical basis that was cooked up, and it wasn't a very good one, because the... Act, not long afterward was struck down as unconstitutional. The president should not have to consult the Senate for firing a cabinet member. But there was a good reason that could have been used in his case. He was fundamentally trying to undo the Union victory in the Civil War. He was unwilling to pursue Lincoln's program of Reconstruction and he was going to be essentially open to all but re-enslaving African-Americans. His programs.. policies... practices showed that he was ripping the country apart, rather than helping to cement the Union that Lincoln had successfully preserved. That wasn't a crime, but it was what the constitution elegantly calls a high crime or misdemeanor and if he had been charged with that... a conviction in the Senate would have been more likely, and more appropriate. So the lesson... is that we should revisit our history, and not simply take the standard views of it as automatically right, and that we should be careful when we use the impeachment power to frame the right reasons for going after a president who has fundamentally broken his compact with the American people and his oath under the constitution.

The defense argues that the Senate should leave the impeachment decision to the voters. While that logic is appealing to our democratic instincts, it is inconsistent with the Constitution’s requirement that the Senate, not the voters, try the president. Hamilton explained that the Founders’ decision to invest senators with this obligation rather than leave it to voters was intended to minimize — to the extent possible — the partisan sentiments of the public. This verdict is ours to render. The people will judge us for how well and faithfully we fulfilled our duty. The grave question the Constitution tasks senators to answer is whether the President committed an act so extreme and egregious that it rises to the level of a “high crime and misdemeanor.” Yes, he did.

Impeachment is a political process, but it has a legal frame of reference... [O]ne of the things we try [very hard] to do in our book... is explain how law and politics interact in this process, and... if you forget the political side, you're going to make a terrible set of blunders. But if you ignore the legal side, you're going to risk destroying the Constitution and the country. I agree, from a strictly partisan, political point of view... that letting Trump basically do himself in and make all kinds of terrible blunders, (and there seems to be a new one every day with this crazy pardon or a completely weird imposition of a tariff that will lose American jobs) that he will make things worse and worse... for himself. But the Constitution we have is a fragile device and if in the course of doing that, he defies judicial orders... He says he might defy an order to submit to a , which would be a first in American history... basically presidents are subject to subpoena, but if he is subpoenaed and as his lawyers said in a memo... he says "No, the president is above the law, above the subpoena power." Then, even though it might be politically wise to just do nothing, we would be breaking faith with the constitution to essentially go back to a system where someone is king. ...Tyrants don't easily give up power, and if we simply let this guy get away with anything, and say, "Let's wait til 2020." It may be too late by 2020 to restore a constitutional democracy under the rule of law.

A well-constituted court for the trial of impeachments is an object not more to be desired than difficult to be obtained in a government wholly elective. The subjects of its jurisdiction are those offenses which proceed from the misconduct of public men, or, in other words, from the abuse or violation of some public trust. They are of a nature which may with peculiar propriety be denominated POLITICAL, as they relate chiefly to injuries done immediately to the society itself.

The historic meaning of the words “high crimes and misdemeanors,” the writings of the Founders and my own reasoned judgment convince me that a president can indeed commit acts against the public trust that are so egregious that while they are not statutory crimes, they would demand removal from office. To maintain that the lack of a codified and comprehensive list of all the outrageous acts that a president might conceivably commit renders Congress powerless to remove such a president defies reason.

There is no basis whatsoever for impeachment. None. There was no collusion. There was no obstruction. There was no crime. The crime was by the Democrats. The crime was by the Democrats. There is no legal basis for impeachment. It's a big witch hunt. Everybody knows it, including the Democrats.

Impeachment requires good judgment amid uncertainty, not a preprinted checklist of relevant considerations...
