Yes, in some lost lazy leftie hazy pre-history the Federal Reserve System would have been considered exterior to the Government, and some sort of Failed pre-911 argument might have been constructable that this was not a Nationalization by the Government. BUT!!!! the nation is @WAR!!!! Therefore there is no such thing as a Federal Reserve System, there is only The War Fed and as such it is an integral part of the Unitary Executive War Command!!!
Thus, one can support AIG, or one is in league with satan stabbing our troops in the back!!!
Which is to say, what role can Congress Have in this? since clearly they gave the president the Majikal Powers, and it is ONLY the War-President who can head up the executive triumvirate against all monsters!!!
So write your congreeCritter and remind them that they should not stab our troops in the back by failing to support the President's Majikal Powers!!!!
