Some reaction to his citizenship bill:

"If they're a U.S. citizen, until they're convicted of some crime, I don't know how you would attempt to take their citizenship away," House Republican Leader John A. Boehner (Ohio) told reporters Thursday, according to Bloomberg News. "It would be pretty difficult under the U.S. Constitution."

I think Lieberman just likes the camera. Or just likes saying things that make progressives say "You're an idiot."
