I think the question is whether he has the right to stop the aid without informing Congress that he is going to do that. I do not know the answer to that question. At the least it is discourteous since members of his own party helped vote for that aid. Businesses in various Congressional districts were affected by these delays and some of them probably had GOP representatives who were apparently uninformed about this stop/delay.
The aid had to go out by the end of the fiscsl year on September 30.
It went out on September 11.
The rest of your post makes no sense at all.
