A good portion of it.
It is beyond ridiculous that this fraud is allowed to continue. And trust me, it is not as if Congress was unaware. In 2013, Paul Ryan and Patty Murray hatched a budget scheme to screw our disabled veterans and retired veterans out of a portion of the pensions.
Senator Sessions and Senator Coburn led an effort to overturn the child tax credit scheme in order to reinstate the money stolen from military pensions.
Senate liberals went nuts, and mounted a full court press to keep the fraud gravy train moving.
It's all on the net if you search. The whole ugly and shameful mess.
