President Trump's impeachment trial began in earnest on Tuesday, with the House impeachment managers and Trump's legal team debating trial rules proposed by Senate Majority Leader Mitch McConnell (R-Ky.). Under McConnell's proposed plan, each side will have 24 hours over three days for opening statements, and senators will have up to 16 hours for questions and four hours of debate. In a 53-47 party line vote, the Senate struck down a proposed amendment from Senate Minority Leader Chuck Schumer (D-N.Y.), who sought to subpoena White House documents and gather further evidence before hearing each argument. Later, the Senate blocked another Democratic attempt to subpoena State Department documents. Democrats have continued to push for new witnesses, while Republicans have argued the trial should include only what was considered in the House.
