MSNBC host Nicolle Wallace called three Fox News personalities “chickenshit” because of their attacks on White House official Lt. Col. Alexander Vindman.

On Monday, Fox News host Laura Ingraham, former Republican Wisconsin Rep. Sean Duffy, and former Justice Department lawyer John Yoo criticized Vindman and seemingly questioned his loyalty to the United States.

MSNBC highlighted reports from each of the three, including a moment when Yoo compared Vindman’s behavior to “espionage.”

Yoo has since clarified his remarks to make it clear he doesn’t believe Vindman was a spy, but that hasn’t stopped many from criticizing the remarks.

On Tuesday, Wallace called the three “chickenshit” for their remarks about Vindman.

In her criticism of the Fox News segment, Wallace compared Vindman to President Trump’s daughter and son-in-law, Ivanka Trump and Jared Kushner, and noted that Vindman had a background check while Trump's family may not have.

“Except those people aren’t chickenshit like the three of you and know he passed a background check that the president’s daughter and son-in-law didn’t,” Wallace said.

Wallace seemed to have surprised herself with her words. After being asked, “Did you just say what I think you said?” Wallace laughed and said, “I don’t know.”

Vindman testified in a closed-door hearing in the House about Trump’s impeachment.
