Alan Dershowitz, the famed defense attorney whose clients included financier Jeffrey Epstein, kicked off his presentation by noting that he would be making the same constitutional argument against impeachment even if the president were Hillary Clinton and not Donald Trump.

He added that he voted for Clinton in 2016, before beginning his argument that in order to impeach a president, a crime must be committed — "abuse of power" alone is not enough. 

Dershowitz argued the opposite in 1998, during the impeachment trial of President Bill Clinton, which Democrats now prosecuting the case against Trump noted days earlier. "It certainly doesn't have to be a crime. If you have somebody who completely corrupts the office of president and who abuses trust and who poses greater danger to our liberty, you don't need a technical crime," Dershowitz said at the time.
