U.S. Senate blocks Democratic amendment to subpoena Department of Defense documents

U.S. Senate republicans blocked democrats' move to subpoena Defense Department documents for the impeachment trial of president Donald Trump on Tuesday. Senators voted along party lines, 53-47, to block four separate motions from Democratic leader Chuck Schumer to subpoena records and documents from the White House, the State Department, the Defense Department, and the Office of Management and Budget related to Trump's dealings with Ukraine.

Trump, who was impeached last month by the Democratic-led House of Representatives on charges of abuse of power and obstruction of Congress, is accused of pressuring Ukraine to investigate former Democratic Vice President Joe Biden, a political rival, and then impeding the inquiry into the matter.
