Three days into his new role representing Montana's diverse 1 million residents as the state's only member of the U.S. House – and after a day of bloody insurrection – Rep. Matt Rosendale said he'd continue to oppose the certification of President-elect Joe Biden's win on Wednesday night.

Sen. Steve Daines, saying he sought national unity, denounced the attempted reversal of the Electoral College roughly two hours earlier - and about seven hours after supporters of President Donald Trump stormed the U.S. Capitol in a violent insurrection.

Daines received recognition for his reversal from Sen. Mitt Romney and other GOP leaders, leaving Rosendale among a small minority of Trump allies supporting the outgoing and disgraced president.

Despite the occupation and desecration of the U.S. Capitol and the violence that played out Wednesday, Rosendale stuck to his position and vowed to oppose the certification of ballots giving Biden the win.

“I will not be intimidated by mob violence from the left or the right. I will oppose certification of electors from certain disputed states,” Rosendale said in a statement.

Rosendale, sworn into office just Monday, announced his plans on Tuesday to oppose the electoral vote in several states.

Despite the violence that ensued at the nation's capital, Rosendale vowed to oppose Biden's “landslide” victory - language Trump used four years ago after winning by the same margin.

“Today is an absolutely terrible day,” Rosendale said. “I have always condemned and will continue to condemn political violence in all forms. It has no place in our country.”

On his second day in office (Tuesday), Rosendale chose to drive a divisive wedge into his chosen language, calling the media “lackeys” and disparaging the outcome of the Electoral College and anyone who opposed the president.

Seasoned Republican leaders took a more unifying tone, saying the nation needed to heal and place the divisiveness of the Trump era behind them.

Daines said as much on Wednesday night, even after serving as a Trump stalwart for several years.

“The senator believed it was best for our nation to move forward with as much unity as possible, and affirm the results,” Daines' office said on Wednesday night.
