“The View” audience audibly reacted to Christie’s refusal to endorse Harris following Tuesday night’s debate.

Joy Behar’s blossoming friendship with her one-time enemy Chris Christie reached a new milestone of tension on live TV, when The View cohost reacted to the former governor of New Jersey’s refusal to endorse Kamala Harris following Tuesday night’s presidential debate.

The moment came as the group discussed undecided voters heading into the November election, with Behar, 81, asking Christie, 62, if Harris’ performance was “going to move the needle” or not for Americans who, before the debate, hadn’t yet backed either Harris or Donald Trump.

“You think you’re going to vote for her now? You were an undecided voter,” Sunny Hostin, 55, asked.

Christie confirmed that he’s “still an undecided voter,” and Behar snapped at the reply.

“Oh, shut up!” Behar said. “Oh, stop it! Boo!”

The show’s in-studio audience also jeered at Christie’s response, prompting moderator Whoopi Goldberg to address the crowd. “Hold up, hold up, hold up,” Goldberg said, opening her arms and turning toward the audience to calm them down.

“I understand you all want me to make some big announcement, but what I will say to you is Donald Trump is not who i’m voting for, you can take that to the bank,” Christie added, while Behar smiled and attempted to hold a side conversation with him as Goldberg attempted to throw the show to a commercial break.

“Joy, hold up!” Goldberg said to Behar, cutting off their chat so she could send the segment off. “Our thanks to Chris Christie. We’ll be right back!”

Since he and Behar put their past feud behind them, Christie has been a regular guest on The View, with his appearances often making headlines for the group’s spirited discussions with the politician.

On a January episode of the show, Christie scolded 35-year-old cohost Alyssa Farah Griffin at the table for “insulting” his supporters with one of her political projections, while Behar later said on the show’s companion podcast Behind the Table that she ultimately forgave her “brutal” feud with Christie because he’s now an enemy of Trump.
