Notorious neoconservative Frank Gaffney may have crossed the line during a heated debate on Afghanistan with Ron Reagan on MSNBC Thursday. Ron Reagan is the liberal son of the late president Ronald Reagan.
"Your father would be ashamed of you," said Gaffney.
"You better watch your mouth about that, Frank," replied Reagan.
MSNBC's Chris Matthews declined to admonish Gaffney for the inappropriate jab.
