What's going on with Stacey Plaskett's aide? Watch this video

Stacey Plaskett was the top Democrat of the day as the FBI testified over the politicizing of the Federal Government. But no one was a bigger viral video moment than Stacey Plaskett's aide who looked like she was being mind-controlled or had crazy eyes. What the hell is going on in this video?

Also, from AP, here's what the context of the video is from:

Former FBI employees accused the bureau of politicization in congressional testimony Thursday, a day after the agency disclosed that two of the men had seen their security clearances revoked over concerns about how their views of the Capitol attack on Jan. 6, 2021, affected their work.The three men alleged overreach and retaliation by the FBI in testimony to a special House committee investigating what Republicans assert is the “weaponization” of the federal government against conservatives.
