For any CAP flight you must receive a flight release authorization. I
would guess that this particular release would come from the AirForce.
Most TFRs don't apply to gov't operations so as long as you are flying
on behalf of uncle sam, you should be ok. There may be some coordiation
required to ensure they know who is coming and going, but most likely
they are waiting for you. Remember that after 9/11 CAP Cessna 172s were
flying over the World Trade Center even before the airlines were back
in the air.
