Hmm...not an attorney here, but even The Waddler must surely realize that the spectacle of a `witness’ being strongarmed out of the House chamber in handcuffs to an uncertain fate would create an instant martyr in the eyes of the public.
Good point on the optics. I am interested in the legal consequences. Can the house actually arrest and detain/incarcerate him, even if only in a private office under guard, (since they don’t have a jail cell)? The Judiciary can do that for contempt of court, but does Congress have the same power? But you are correct that the optics would be a riot and Lewendowski would love to have the House do it since it would give him publicity for his Senate run.
