READ THIS. He essentially line edited it. This is VERY important to read. The constitution give certain powers to the executive that can't be written away in a bill by Congress. Trump has given them notice that these are not legal and won't be heeded.

The Congress cannot enact an illegal law. Trump does not have to submit to an illegal law.

According to this site he hasn't signed it yet, maybe he's going the pocket veto
