While Senate Majority Leader McConnell has locked up enough Republican votes to ignore demands for a bipartisan framework for President Donald Trump’s impeachment trial, his Democratic counterpart is readying a counteroffensive. Schumer will force a series of votes designed to squeeze vulnerable Republicans and harm them on the campaign trail if they side with Trump.

Democrats argue the half-dozen at-risk GOP senators will need some daylight between them and Trump to get reelected. And if they vote against Schumer’s motions to hear new evidence and witness testimony, they’ll be seen as Trump sycophants — undermining their bids and boosting Schumer’s odds of becoming majority leader.

Support for obtaining new documents at the trial is “even stronger than we thought, with large numbers of Republicans supporting it,” Schumer (D-N.Y.) said in an interview. “And when you go against what the American people feel strongly about, on an issue they’re paying attention to, it’s not a good idea.”
