Romney, a devout Mormon, frequently invoked his faith in a brief speech from the Senate floor on Wednesday afternoon, when he announced his intention to vote in favor of the first impeachment article charging Trump with abuse of power.

Already a strong Republican critic of the administration, Romney acknowledged the fierce onslaught he expected to receive from his own party as the only GOP lawmaker to break ranks and vote to convict the president.

“I’m aware that there are people in my party and in my state who will strenuously disapprove of my decision, and in some quarters I will be vehemently denounced,” he said in his prepared remarks. “I’m sure to hear abuse from the president and his supporters. Does anyone seriously believe that I would consent to these consequences other than from an inescapable conviction that my oath before God demanded it of me?”

The editorial board noted that Romney knew his decision would not change the outcome of the ultimate vote by the Senate — which acquitted Trump of both impeachment articles Wednesday afternoon — and acknowledged that the president “is in a position … to make life very difficult for Romney going forward.”

Romney has been subjected to numerous attacks by the White House and its conservative allies in the hours since casting his vote in the Senate impeachment trial, with the president weighing in Thursday morning.

“Had failed presidential candidate @MittRomney devoted the same energy and anger to defeating a faltering Barack Obama as he sanctimoniously does to me, he could have won the election,” Trump tweeted. “Read the Transcripts!”
