Schiff thanks senators at the start of impeachment argument after Nadler accused Republicans of 'voting for a cover up'

Democrats officially kicked off their opening arguments in the impeachment trial of President Trump Wednesday with a bit of a shift in tone after one particularly contentious late-night exchange.Near the end of an impeachment trial session beginning Tuesday, House Judiciary Committee Chair Jerrold Nadler (D-N.Y.) on the Senate floor accused Republican senators of "voting for a cover up" as he argued in favor of an amendment to subpoena former National Security Adviser John Bolton, per The Wall Street Journal. Nadler also suggested Republicans were engaging in "treacherous" behavior, The Washington Post reports. Republicans throughout the day on Wednesday slammed Nadler for his statement; Sen. John Cornyn (R-Texas) told CNN it was "insulting and outrageous," while Sen. Lisa Murkowski (R-Alaska) said the comment "offended her" and Sen. Lindsey Graham (R-S.C.) said in a press conference, "To my Democratic colleagues, you can say what you want about me but I am covering up nothing."Following this criticism, House Intelligence Committee Chair Adam Schiff (D-Calif.) began Democrats' opening arguments Wednesday with a less combative tone, thanking senators for having "paid attention to every word and argument you heard from both sides" the day before."I want to begin today by thanking you for the conduct of the proceedings yesterday and for inviting your patience as you go forward," Schiff added. "We have some very long days yet to come."CNN's Kaitlan Collins noted Schiff appeared to be addressing Republican criticism with his opening comments, although Republicans weren't the only ones not thrilled with the tone of Tuesday night's debate. Sen. Jon Tester (D-Mont.), for instance, conceded to The Washington Post that Nadler "could have chose better words."More stories from theweek.com Prosecutor slams Weinstein's 'complete lack of empathy' as opening arguments begin Several senators left the chamber in the middle of Adam Schiff's impeachment remarks Trump outright brags he's withholding 'all the material' to beat impeachment
