The best advice Newt gave was for Cain to be accurate. Should he not be, it will come back to bite him.
yeah, Newt assumed the accusations true and demanded Cain prove them lies.
Gingrich just validated the Guilty until proven innocent propaganda meme the Democrat/GOP Media machine is pushing.
Rather then demanding the media prove the accusations, he is demanding Cain disprove the accusation.
Newt threw Cain under the bus. Good old Newt, in the end he just could not help being a good little GOP Establishment Media whore.
