The exchange went on with Mullin still trying to turn his time into a fight promo (you can watch at the link below), and O’Brien reminding Mullin that he had the opportunity to be one of the most “influential people in the country but you’re focused on debate that isn’t even relevant. You’re an embarrassment. An embarrassment.” The truth clearly continues to hurt Mullin.

The bad blood goes back to March, when the two men got into a heated argument during another Senate Health, Education, Labor, and Pensions Committee hearing. O’Brien called out Mullin’s anti-labor “tough guy” schtick and the two exchanged barbs. Mullin came out looking pretty pathetic. O’Brien continued besmirching Mullin’s not-great name on social media, and in June, Mullin challenged O’Brien to a MMA-style fight for charity.

Mullin’s “self-made” business was originally his father’s, which he took over when his father got ill. Still, there are many questions about how he got so gosh-darned rich, as The New Republic reported earlier this year:

Mullin himself warrants his own level of scrutiny as to whether he is an “honest” millionaire. The Oklahoma Republican was already swimming in assets worth up to $29.9 million in 2020. The following year, his net worthexploded to be anywhere between $31.6 million and a gargantuan $75.6 million. Mullin received some $1.4 million in federal PPP loans and was among the members of Congress who helped tank the TRUTH Act, which would have required public disclosure of companies receiving those relief funds.

Pathetic.

And there’s always a tweet with guys like this.
