The Senate voted 53-47 to acquit Trump on the second article of impeachment,which accused him of obstruction of Congress.
All the Senate Democrats voted to convict Trump but they would have required a"supermajority"of 67 votes to remove him from office.
Republican Senator Mitt Romney announced earlier in the day that he would vote to remove Trump,citing his deep religious faith as a key factor in his dramatic decision.
"Corrupting an election process in a democratic republic is about as abusive and egregious an act against the Constitution - and one's oath - that I can imagine,"Romney said on the Senate floor.
"It's what autocrats do."
