A letter signed by 520 legal scholars states the case very clearly. “President Trump engaged in impeachable conduct... If the House of Representatives impeached the President for the conduct described here and the Senate voted to remove him, they would be acting well within their constitutional powers.”

Professors from Harvard, Stanford, and numerous other colleges and universities are on the list. Here’s an excerpt from the letter: 

We do not reach this conclusion lightly. The Founders did not make impeachment available for disagreements over policy, even profound ones, nor for extreme distaste for the manner in which the President executes his office. Only “Treason, Bribery, or other high Crimes and Misdemeanors” warrant impeachment. But there is overwhelming evidence that President Trump betrayed his oath of office by seeking to use presidential power to pressure a foreign government to help him distort an American election, for his personal and political benefit, at the direct expense of national security interests as determined by Congress. His conduct is precisely the type of threat to our democracy that the Founders feared when they included the remedy of impeachment in the Constitution.

We take no position on whether the President committed a crime. But conduct need not be criminal to be impeachable. The standard here is constitutional; it does not depend on what Congress has chosen to criminalize.
