Senators began debate Tuesday afternoon over the rules that will guide the impeachment trial of President Trump — just the third in history of a U.S. president — focused on his conduct toward Ukraine.
The Senate also rejected amendments to subpoena Trump administration officials, including acting White House chief of staff Mick Mulvaney; his senior adviser, Robert Blair; and top Office of Management and Budget official Michael Duffey. Each amendment was tabled on a 53-to-47 party-line vote.
