Sen. Mike Lee (R-UT) during a Monday debate called out Evan McMullin’s lies about January 6.

McMullin, a Utah independent Senate candidate, said Lee was a traitor to the Constitution.

Lee, indignant at McMullin’s bold claim, said, “You know that’s not true. You, sir, owe me an apology.”

He continued:

In the days leading up to January 6, when the votes were going to be open and counted, I had a job to do, there were rumors circulating that some states were considering switching up their slates of electors. If that were true I would need to know about it. I did research on that, I did phone calls on that, but the rumors were false. On that basis I voted to certify the results of the elections.

Matt Whitlock, a former senior staffer for the late Sen. Orrin Hatch (R-UT), said, “This is so pathetic. @EvanMcMullin is such a deeply unserious candidate who pushed conspiracy theories about Russia stealing the 2016 election for the last 6 years.”

McMullin has also appeared to be a strong supporter of the theory that Russia intervened in the 2016 presidential election to help then-candidate Donald Trump win the 2016 presidential election.
