Senate Republicans signaled Monday they would reject the idea of simply voting to dismiss the articles of impeachment against President Donald Trump as the House prepares to send the charges to the chamber for the historic trial. It will be only the third presidential impeachment trial in American history, a serious and dramatic endeavor coming amid the backdrop of a politically divided nation and the start of an election year. Speaker Nancy Pelosi has not set the timing for the House vote that will launch the Senate action.
