Fox News host Chris Wallace, a registered Democrat, faced intense backlash on Tuesday night for what was widely deemed as bias in the debate in the favor of Democrat Joe Biden and against Republican President Donald Trump.

One of the issues that Wallace was called out for the most was how he appeared to let Biden interrupt Trump but would jump in to interrupt Trump when Trump would talk over Biden.

Fox News host Brian Kilmeade even noted the discrepancy and called it out on social media, writing: “Why is @JoeBiden allowed to interrupt? @realDonaldTrump is not.”

Bill O’Reilly, who used to be a colleague of Wallace’s, wrote on Twitter: “Good line from Trump—he tells Chris Wallace he’s debating him, not Joe.”

Wallace added: “Chris Wallace doesn’t have the facts at his command about the Ukraine payments made to Biden’s son that Trump brought up. Big mistake by Mr. Wallace.”

Attorney Harmeet Dhillon wrote on Twitter: “Chris Wallace is a disgrace. Republicans need to stop allowing the slanted media to have any role in debates in future years.”

Actor James Woods wrote on Twitter: “Chris Wallace is shamelessly biased. It’s a beautiful demonstration of fake news in action. I’m actually glad it’s happening, because you can see it for yourself.”

Journalist Yashar Ali, who was Hillary Clinton’s co-chair on her 2008 presidential campaign, wrote on Twitter that there was “no doubt” that “Wallace is not doing a good job as a debate moderator.”

Newsweek editor Josh Hammer wrote on Twitter: “Just an inexcusable effort tonight from Chris Wallace. And I say that as someone who is generally a fan of his.”

Federal co-founder Sean Davis wrote on Twitter: “Chris Wallace is now reading Biden’s energy plan back to him to remind Biden what’s in his plan. I have never, never seen anything like this from a moderator.”

Davis added: “Chris Wallace is making very clear that his goal tonight is to run interference for Joe Biden. If he wants to be a deranged NeverTrumper, that’s his prerogative, but Wallace is doing everything in his power to tilt the election toward his preferred candidate. Everyone can see it.”

Ben Shapiro wrote on Twitter: “Chris Wallace, over the course of the night, has moved from moderator to debater.”

Conservative commentator Jesse Kelly wrote on Twitter: “Ok, I don’t generally nitpick moderators, but Chris Wallace asking Joe Biden about the ‘very fine people’ thing without bringing up that it’s a flat-out lie is an absolute embarrassment.”

Former Acting Director of National Intelligence Richard Grenell tweeted: “Chris Wallace is supposed to be invisible. He isn’t. He’s off to a terrible start.”

Grenell added: “Chris Wallace doesn’t interrupt Joe Biden.”

Commentator Candace Owens tweeted: “Unbelievable. Every person in America knows these riots are being orchestrated by black lives matter and Antifa. Chris Wallace asks the President to condemn white supremacists but did not think to ask Joe Biden to condemn Antifa or BLM.”

Political commentator Harry Khachatrian tweeted: “Chris Wallace chuckling and joking with Biden during the debate, mid-question is grossly unprofessional conduct from a moderator.”

Conservative commentator Ann Coulter wrote: “Every time Trump is nailing Biden, Chris Wallace interrupts. ‘That’s the next topic!’”

MSNBC host Joe Scarborough wrote: “Where is Chris Wallace? This is a disgrace.”

Former White House doctor Ronny Jackson tweeted: “Fire Chris Wallace! He is an embarrassment to Fox News!!”

Former CNN host Soledad O’Brien wrote: “Hellllo Chris Wallace??? Looking for a moderator here. Jesus Christ what a fricken mess.”

Leftist Mikel Jollett wrote: “Dear Chris Wallace: You are a national embarrassment.”

Conservative Dana Loesch wrote on Twitter: “Never allow Chris Wallace to moderate another debate again. This was an absolute shit show. The viewer wasn’t even a secondary concern.”
