Donald Trump Mocks Mitt Romney After Utah Senator Joins Black Lives Matter March

President Donald Trump mocked Sen. Mitt Romney after the Utah Republican joined with other Christians marching to the White House in support of the Black Lives Matter movement.

Romney, who was the Republican nominee at the 2012 election, has clashed with Trump before and voted to convict the president in the Senate after his impeachment by the House of Representatives.

The 73-year-old is a devout Mormon and recently posted an image to Twitter of his father, the late former Michigan Gov. George Romney, joining civil rights protesters in the 1960s.

In a short video clip of the younger Romney as he marched with Christians in D.C. on Sunday, the senator told a Washington Post reporter he joined in "to end violence, and brutality, and to make sure that people understand that black lives matter."

On Monday morning, Trump shared the clip on his own Twitter account, and the president wrote: "Tremendous sincerity, what a guy. Hard to believe, with this kind of political talent, his numbers would 'tank' so badly in Utah!"

Newsweek has asked Romney's office for comment.

A Deseret News/Hinckley Institute of Politics poll in early May gave Romney a net approval rating among Utahns of plus 14 percent, though 10 percent of the 984 voters surveyed were not sure. There was a 3.2 percentage point margin of error.

Another 2News poll in early June also gave Romney a net approval rating of plus 14 percent.

Just 1 percent of the 1,099 likely Utah voters surveyed said they did not know what to think of the job their senator was doing. The poll had a 3 percentage point margin of error.

The Trump-Romney feud dates back to before the 2016 election and has regularly resurfaced around various issues. The president's barbed comments over Romney's attendance of the march in Washington D.C. is the latest exchange.

In April, when the White House launched its Opening Up American Again Congressional Group to tackle the coronavirus pandemic, all Republican senators were listed as members—except Romney.

The month before, Trump tweeted sarcastically about Romney's negative test for the coronavirus: "This is really great news! I am so happy I can barely speak. He may have been a terrible presidential candidate and an even worse U.S. Senator, but he is a RINO, and I like him a lot!" RINO stands for "Republican in name only."

Their relationship had reached its nadir in January when Romney was the only Senate Republican to vote that Trump was guilty of abuse of power, one of the impeachment charges, over the Ukraine affair.

Speaking at the time, Romney accused Trump of "a flagrant assault on our electoral rights, our national security and our fundamental values."

"Corrupting an election to keep oneself in office is perhaps the most abusive and destructive violation of one's oath of office that I can imagine," Romney said in his speech to the Senate.
