Think about Pelosi’s position...She had to (possibly was forced to/blackmailed) manipulate the paper work so he wouldn’t be found out...and she may end up doing time for it....A good reason not to want to cooperate any more....He11 yes I’d be angry at him, myself for getting in that position....What are her options for getting out of it? Not many...alive.
But consider this, she does know how she covered Obama’s ass in Hawaii with that second certification which was her certifying FOR Hawaii that Obama was constitutionally eligible to run for POTUS. Is she mad enough to reveal THAT?
