WASHINGTON (AP) — President Donald Trump appears poised for acquittal in his impeachment trial. Senators are preparing to vote late Friday to reject efforts to call more witnesses and instead start bringing a close to the third such trial in American history. Democrats’ hopes of prolonging the trial dimmed after a late decision from Republican Sen. Lamar Alexander of Tennessee to oppose calling more witnesses. Timing of a final vote on acquittal is still up in the air. But Trump wants it over before next Tuesday’s State of the Union Address.
