Actually the Constitution ensured that Congress has and retains the power of the purse. It's just that RINOS and their leftist political allies are so concerned with stealing as much wealth and power for themselves while residing in their 'sinecure for life' jobs that they won't anymore exercise that power.
LOL . . . nobody stole it. All Congress has to do is act, but it never does -- regardless if leftists or the overwhelming numbers of RINOS infesting the GOP mutually 'agree' never EVER to exercise that iron clad Constitutional right.
