After replying to questions for the White House legal team several times on Wednesday, Dershowitz was not present on the Senate floor for Thursday's Q&A session.
At one point on Wednesday, Dershowitz said of the office of the President, "The President is the Executive Branch. He is irreplaceable."
In a series of posts on Twitter Thursday morning, Dershowitz claimed that his remarks were misinterpreted by the media and legal critics.
"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," Dershowitz said Wednesday.
In arguments on Thursday, Schiff said what Dershowitz told the Senate would take the nation back to where things were with President Nixon in Watergate.
"We may be in a worse place," Schiff said about the current controversy with President Trump, "because this time, that argument may succeed."
