"Very few times I’ve felt threatened while out in the field. The mood here tonight is very volatile. Law enforcement appears to be closing down 1st Street in front of [the Supreme Court]," Bream wrote shortly after the president announced his selection of Kavanaugh to replace retiring Supreme Court Justice Anthony Kennedy from the White House East Room.

"Literally had to bail on our live show from #SCOTUS. Moving the show back to the safety of the studio. See y’all at 11p @FoxNews," she added in another tweet less than 40 minutes before her show, "Fox News @ Night," was set to begin.

Hundreds of protesters were estimated to be outside the court. They were joined at one point by Sen. Bernie Sanders Bernie SandersOutrage erupts over Breonna Taylor grand jury ruling Dimon: Wealth tax 'almost impossible to do' Grand jury charges no officers in Breonna Taylor death MORE (I-Vt.), who warned that Kavanaught's confirmation could lead to the overturning of the Roe v. Wade decision on abortion.

“Are you ready for a fight? Are you ready to defend Roe vs. Wade?" Sanders said, according to a report by USA Today.

“This is a tough fight but it is a fight that we can win. ... We have the American people on our side, now we have to go state by state by state to make sure senators do what their constituents want,” the outlet quoted the senator as stating.

Right-leaning media members were quick to blame the left for Bream's decision to move her program.
