(Reuters) - The U.S. Senate is holding an impeachment trial on charges by the House of Representatives that President Donald Trump abused his powers and obstructed a congressional inquiry into his effort to pressure Ukraine to investigate Democratic presidential contender Joe Biden.
The Republican-controlled Senate faces a bitter fight over whether witnesses and new documents should be part of the trial when it resumes on Monday, or whether the 100 senators should just rely on information presented by the House, as well as the rebuttal from White House lawyers arguing for Trump's acquittal.
