Nearly 1,000 attorneys—including Berkeley Law’s Erwin Chemerinsky and Harvard Law’s Laurence Tribe—are asking California bar authorities to investigate conservative attorney John Eastman for allegedly working in concert with other lawyers to try and install former President Donald Trump in a second term, despite having lost reelection.

The complaint, filed Thursday by the group Lawyers Defending American Democracy, spotlights Trump lawyer Rudy Giuliani and former Trump DOJ official Jeffrey Clark as having worked congruently with Eastman. “We believe that concerted unethical action by lawyers aggravates the circumstances of their violation,” the complaint reads. More than 1,200 people signed the complaint, including more than 200 nonlawyers.
