Democratic lawmakers are continuing to lay out their case for removing the president from office in the final day of opening arguments by Democrats in the historic impeachment trial of President Trump. Republicans will begin their opening arguments on Saturday. The Senate trial comes a month after the House impeached Trump for withholding congressionally approved military aid to Ukraine as part of an effort to pressure the Ukrainian president to investigate Trump’s political rival, Democratic presidential candidate Joe Biden. On Thursday, House impeachment manager Jerrold Nadler made the case that a president can be impeached for noncriminal activity. During another part of Thursday’s proceedings, House impeachment manager Congressmember Sylvia Garcia relied on polls by Fox News to make the case that President Trump decided to target Joe Biden after polls showed the former vice president could beat Trump in 2020. For more on the impeachment trial, we’re joined by Marjorie Cohn, professor emerita at Thomas Jefferson School of Law and the former president of the National Lawyers Guild. Her most recent book is “Drones and Targeted Killing: Legal, Moral, and Geopolitical Issues.”
