A controversial Republican senator openly declared he chose not to support his party leader at the upcoming election.

Sen. Mitt Romney (R-Utah) has admitted to the press he did not vote for President Donald Trump during early voting for the 2020 general election.

“Mitt Romney told me he already voted in the elections but he would not say if he voted for Joe Biden or wrote someone else in,” CNN senior congressional correspondent Manu Raju said on Twitter. “‘I did not vote for President Trump,’ he said.'”

Romney refused to confirm exactly who he voted for but suggested he might reveal who his first choice was to lead the country after polling stations close on Nov. 3.

“Asked whom he voted for, Romney said: ‘That is something I am keeping private at this stage,'” Raju said on Twitter.

The remarks came despite overwhelming support from other Republican Party members who favored President Trump having another four years in the Oval Office.

“96 percent approval rating in the Republican Party,” the president said on Twitter back in June. “Thank you!”

The president suggested the disgruntled senator could have won the 2008 presidential election if he showed the same level of enthusiasm when campaigning against then-Democratic candidate Barack Obama.

“If Mitt Romney spent the same energy fighting Barack Obama as he does fighting Donald Trump, he could have won the race (maybe),” the president said on Twitter.

American Conservative Union Chairman Matt Schlapp previously withdrew Romney’s invitation to attend the 2020 Conservative Political Action Conference (CPAC) in National Harbor, Maryland.

Schlapp explained the decision to disallow the “extreme conservative” was not taken lightly. The senator’s failure to follow the Republican Party in calling no further witnesses and evidence for the president’s impeachment trial was the last straw.

“[CPAC] formally disinvite[s] someone who has been particularly egregious,” Schlapp told Fox News. “Mitt Romney deserved this [because] his Senate tenure is a waste and his vote [in the Senate] was the latest outrage.”

The senator had posted a statement ahead of the impeachment trial, echoing the views of Democrats. They defended their decision to impeach the president because it was their duty to uphold the Constitution.

“I feel a deep sense of responsibility to the Constitution, to the people of Utah and to the nation,” Romney said. “I and all senators swore an oath to ‘do impartial justice according to the Constitution and laws: so help me God’ in determining whether the president has committed impeachable offenses that merit his removal from office … I enter this task with an open mind and a recognition of my solemn responsibility to fulfill my oath.”
