Republican Romney Says He'll Vote To Convict Trump

Republican Senator Mitt Romney of Utah said US President Donald Trump is guilty of an "appalling abuse of public trust" and he will vote to convict him later Wednesday at his Senate impeachment trial.

"Corrupting an election to keep one's self in office is perhaps the most abusive and destructive violation of one's oath of office that I can imagine," the 2012 Republican presidential candidate said.

"The president is guilty of an appalling abuse of public trust," he said in a somber speech on the Senate floor just hours ahead of the historic vote.

Romney is likely to be the only Republican voting to convict Trump when the Senate considers the House of Representatives articles impeaching the president for abuse of power and obstruction of Congress.

Romney said it was the "most difficult decision I have ever faced" and he expected he would come in for harsh criticism from fellow Republicans.

"I'm aware that there are people in my party... who will strenuously disapprove of my decision, and in some quarters I will be vehemently denounced," he said.

But he said it was a matter of conscience and in accordance with his Mormon faith.

"As a senator juror, I swore an oath before God to exercise impartial justice," he said.

"With my vote, I will tell my children and their children that I did my duty to the best of my ability," Romney said.

Trump was impeached by the Democratic-controlled House on December 18 for withholding military aid to Ukraine to pressure Kiev to investigate his potential November election rival Joe Biden.

Republicans hold a 53-47 majority in the Senate and a two-thirds majority -- or 67 senators -- is needed to remove a president from office.
