Harvard Law School professor emeritus Alan Dershowitz on Thursday found himself facing a new round of criticism for his remarks defending President Donald Trump at his impeachment trial on charges of abuse of power and obstruction of Congress.

“Every public official that I know believes that his election is in the public interest. Mostly you are right. Your election is in the public interest,” Dershowitz said Wednesday during the question-and-answer session of Trump’s trial, which is set to continue this afternoon in the Senate. “If a president does something which he believes will help him get elected in the public interest, that cannot be the kind of quid pro quo that results in impeachment.”
