Markwayne Mullin is unbowed after nearly coming to blows in a hearing Tuesday: "I’m not afraid of biting."

Sen. Markwayne Mullin (R-Okla.) is making clear he isn't afraid of a fight — or using unconventional tactics in a donnybrook.

"I'm not afraid of biting. I will bite," he said in an interview with a local podcast, "Undaunted Life: A Man's Podcast." "I don't care where I bite, by the way."

The comments, first flagged by Democratic super PAC American Bridge, came after Mullin nearly came to blows with Sean O'Brien, the president of the International Brotherhood of Teamsters, during a Tuesday hearing where Sen. Bernie Sanders (I-Vt.), the chair of the HELP Committee, had to intervene.

Mullin went on to say: "I'm still a guy from Oklahoma."

"I'm not a very good Christian — I try to be a good Christian," he said. "I won't start it, but I'll sure do everything I can to finish it."
