WATCH: Trump supporters heckle Mitt Romney on DC bound flight and call him a 'traitor'

Senator Mitt Romney (R-UT) was heckled and called "traitor" by passengers on a plane boarded to fly from Salt Lake City, Utah to Washington, DC.

Prior to boarding the plane, Romney was confronted by a woman who said she was one of his constituents as he waited at the gate for his flight. She demands to know why Romney is not supporting Trump's claims of voter fraud.

"Why aren't you supporting President Trump?" She asks.

Romney asks her to put her mask on to which she responds, "Don't tell me what to do, I'm standing six feet away. You know what I'm going to go ahead and do it because I want to have a chat with you."

The woman demands to know why Romney does not support President Trump. The Senator responds, "I do support President Trump. I'm sorry, I do agree with many of the things he's for and I support him."

"You were voted in as a conservative to represent the conservative constituents, period," she said. She went on to say that "You're voted in to represent us, you were voted in to represent us, you work for us, am I wrong?" She asked.

There's alot of people who didn't vote for you, we'll make sure of that one," she said. "They didn't want you in there anyway," she said

They then engage in a "spirited" discussion over the constitutional ramifications of the election outcome which ends with the woman saying "I wouldn't be surprised if you weren't even voted in legally, you're a joke, an absolute joke, it's a disgusting shame."

Once aboard the plan, Trump fans take up the chant of "traitor" aimed at the senator. They called on him to resign, and wanted to know his connection to Burisma and the Biden family.

"Mitt Romney you don't listen to your constituents!" A passenger shouted.

Romney on Saturday slammed Trump's claims that there was fraud in the presidential election as a "false rumor." The former Republican presidential candidate and longtime critic of the President added that attempts by some Republicans to stand against Joe Biden's win "dangerously threatens our Democratic Republic."

Thousands of Trump supporters were on route to Washington, DC, to attend a rally in support of the President on Wednesday while Congress meets to certify the votes of the Electoral College. Romney is among a group of Republican Senators who oppose the effort by others in their party to object to the results of the election. Over 140 members of the House of Representatives as well as a handful of senators have stated their intention to vote against certification.
