US Senate Resumes Questioning in Trump Impeachment Trial Ken Bredemeier The U.S. Senate on Thursday held a final day of questioning President Donald Trump's defense team and the House lawmakers prosecuting his impeachment case, as a decision looms about allowing witnesses. Trump attorney Alan Dershowitz argued on Wednesday that even if Trump did ask Ukrainian President Volodymyr Zelenskiy for a political favor in exchange for aid, it is not impeachable. "Every public official that I know believes that his election is in the public interest ... and if a president did something that he believes will help him get elected, in that public interest, that cannot be the kind of quid pro quo that results in impeachment," he said. The lead prosecutor, Democrat Adam Schiff of the House Intelligence Committee, maintained Dershowitz's argument lacks merit. .
