Former President Trump celebrated Sen. Mitt Romney (R-Utah) being booed by a crowd by fellow Republicans at an event last week, calling the senator “a stone cold loser.”

“So nice to see RINO Mitt Romney booed off the stage at the Utah Republican State Convention,” Trump said in a Monday statement, using the acronym for the dig “Republican in name only."

“They are among the earliest to have figured this guy out, a stone cold loser!” Trump continued. 

Romney was booed on Saturday at the beginning of his speech at the Utah Republican Party’s organizing convention.

Video from the speech showed attendees cheering and booing after Romney asked how people felt about President Biden’s first 100 days in office.

Booing from the crowd became louder after Romney said he wasn’t a fan of Trump’s “character issues.” 

“You know me as a person who says what he thinks, and I don’t hide the fact that I wasn’t a fan of our last president’s character issues,” Romney said, receiving more boos before he asked the crowd, “Aren’t you embarrassed?”

The Utah GOP during the convention narrowly voted against a resolution to censure Romney over his votes to convict Trump during both of his impeachment trials.

The Republican senator has been a vocal critic of the former president. 

Romney earlier this year was also one of several GOP senators who voted to convict Trump for inciting the deadly riot at the U.S. Capitol on Jan. 6. He also voted to convict Trump on one count during his 2020 impeachment trial.

Trump has repeatedly slammed Romney, including criticizing his impeachment votes and mocking him for attending a Black Lives Matter march in Washington, D.C., last year.
