He will not be under oath. Waste of time.
Lying or ‘materially misleading’ Congress is a felony regardless of whether an oath is administered. When an oath is sworn in Congressional hearings, it’s just a scene for the TV show.
“Waste of time.”
Good propaganda, though. I bet he says enough to get low-information voters all fired up about the “need for regulation” to prevent anyone but progressives to use data mining tools in elections.
Couple that with nationalized elections (to prevent Russian Hacking) and it just might sew it all up.
