Fox News anchor Sandra Smith has become the subject of Twitter buzz after a now-viral clip showed her off-camera reaction to the comments of a guest during the network’s Saturday broadcast.

In the video circulating on social media, Smith squinted her eyes and shook her head while DC-based lawyer Cleta Mitchell said “just because CNN says — or even Fox News says — that’s somebody’s president, doesn’t make them president.”

Major networks such as CNN, the Associated Press as well as Fox News reported Democratic nominee Joe Bid3n surpassed 270 electoral votes and secured the race for president Saturday after Pennsylvania was finally called for the former vice president.

Smith, whose microphone was still on, responded to Mitchell’s comments with incredulity.

“What? What is happening? Trace, we’ve called it,” she says to her co-anchor, Trace Gallagher, who didn’t respond in the moment.

When reached for comment, Mitchell directed USA TODAY to a tweet she posted on the topic.

“Sandra Smith thinks Fox News calling the election means Bid3n is President. Forget that pesky Constitution… happy to be considered a nut job because I believe in the rule of law,” she wrote on Monday alongside the viral clip.

On Monday, meanwhile, Fox News’ Neil Cavuto broke into coverage of Kayleigh McEnany’s Tr::ump campaign news conference Monday and abruptly pulled the plug following unsubstantiated and “explosive” claims of voter fraud.

White House press secretary McEnany, a federal employee speaking in a “personal capacity” as a Tr::ump campaign adviser and spokesperson, was explaining President Donald Tr::ump’s refusal to concede election.

Shortly after McEnany’s claim that the Democratic Party was “welcoming fraud” and “welcoming illegal voting,” Cavuto appeared at his desk on Fox’s split screen and stopped the network’s live coverage.
