Looking for a weird man at the congressional hearings

I'm looking for a post/video regarding a weird looking man in the congressional hearings who was just staring and blinking with only one eye.

That video made me a little bit uneasy and it was taken from the congressional hearings livestream in november iirc.

Been looking for a few hours and nothing, does anyone where that is? I remember there were actually two individuals who were... weird. But I solely remember the last one I mentioned above.
