The War Powers Act requires the president to consult with Congress before carrying out any military strikes overseas.
He didn't.
The president is in violation of the War Powers Act and Congress has an obligation to reassert its authority. I get it him doing it was for a purpose, but the dude continues to say fuck with the rules and isn't it interesting he does this when he has his Impeachment going on. Almost like he did it to try and try to ease the problems with that so he can get praise for what he did?
