By Trump declaring a Human Rights Emergency AND has notified Congress that he's invoking the Balanced Budget and Emergency Deficit Control Act of 1985, this opens up new spending options. 6. President Trump has just communicated that he has the authority to NOT spend any funds he doesn't deem necessary and will return them to the US Treasury. For example: funds the House allocated for Planned Parenthood? Trump can simply not allocate the funds ...
Trump's declarations also make some funds fungible. For instance if he determines that building a Wall on the Southern Border is a defense against Human Trafficking? He can move funds from anywhere else in the Defense Dept Allocation & simply build the Wall.
8. Congress is powerless to stop cash reallocations AND cannot stop the DOD from taking measures under a presidential-declared Emergency.
Despite the House's strict language about the Border Wall, it is outweighed by Trump's declaration of a State of Emergency.
Trump needs to use these powers - he has nothing to lose. The press will hate him whatever he does, democrats will hate him no matter what he does, Democrat War Rooms will still send him hate letters written so they sound like they come from his base... TRUMP HAS NOTHING TO LOSE BY DOING IT HIS WAY - AND EVERYTHING TO GAIN.
Trump probably intends to use powers seldom used before his ascension to the presidency. Gonna be fun to observe.
