(JTA) – Alan Dershowitz, the constitutional scholar, will join President Trump’s impeachment defense team. “Professor Dershowitz will present oral arguments at the Senate trial to address the constitutional arguments against impeachment and removal,” New York Times reporter Maggie Haberman quoted Trump’s legal team as saying on Friday, Jan. 17. The team is led by Pat Cipollone, the White House counsel, and Jay Sekulow, Trump’s personal lawyer. Also joining is Ken Starr, who as an independent counsel led the impeachment proceedings against President Bill Clinton in the late 1990s.

Dershowitz, although he was not part of Clinton’s defense team, robustly defended the president in opinion pieces and on television during Starr’s proceedings. Now they will be on the same team. “While Professor Dershowitz is nonpartisan when it comes to the Constitution – he opposed the impeachment of President Bill Clinton and voted for Hillary Clinton – he believes the issues at stake go to the heart of our enduring Constitution,” the statement said.

Dershowitz, a Harvard law professor and author, is a prominent defender of Israel and has consulted with Trump on his Israel policy. He has appeared on cable news as a defender of Trump during the recent impeachment crisis and is often touted by Trump defenders as a liberal who is defending a conservative president on principle.
