Democratic House impeachment managers are expected to argue Friday that President Donald Trump obstructed Congress' investigation into his dealings with Ukraine. It's the final day for the seven House managers, led by Intelligence Chairman Adam Schiff, D-Calif., to state their case that Trump should be convicted and removed from office. On Thursday, Democrats laid out their arguments that Trump met the standard for impeachment by pushing Ukraine President Volodymyr Zelenskiy to announce probes into his political rivals and a debunked conspiracy about the 2016 presidential election while millions of dollars in congressionally approved military aid to Ukraine was being withheld. Schiff gave an impassioned speech late Thursday at the close of the day's proceedings, folding a searing attack on Trump's character into a sweeping appeal to senators' common sense. In America, Schiff said, "Right is supposed to matter."

"It's what's made us the greatest nation on Earth. No Constitution can protect us if right doesn't matter anymore, and you know you can't trust this president to do what's right for this country. You can trust he will do what's right for Donald Trump." The proceedings ended around 10:30 p.m. ET. When the Senate convenes at 1 p.m. Friday, Democrats are expected to detail their argument that Trump, by refusing to hand over any documents to the House and by pressuring witnesses not to cooperate with the impeachment inquiry, is guilty of obstruction of Congress. The Democrats have 24 hours total, spread out over three days, to state their case. Trump's lawyers will have the same time to present the president's defense. They are expected to start Saturday — a time slot that Trump grumbled about on Twitter as "Death Valley in T.V." Trump TWEET Senators, who are required to remain silent during the trial proceedings, will then have 16 cumulative hours to ask questions of the House managers and the defense team in writing. Under Republican Majority Leader Mitch McConnell's rules, the Senate will then get to vote on whether to produce documents and witnesses in the trial that Republican and Democratic lawmakers have been pushing for. Amendments to issue subpoenas beforehand for a slew of documents and witnesses were shot down Tuesday. But Senate Minority Leader Chuck Schumer, D-N.Y., has pressed Republicans to support calling witnesses when it comes up for a vote. Democrats need four Republicans to vote with them. Even if they win that battle, it remains unlikely that two-thirds of the Senate will vote to convict and remove the president from office.
