US Politics in Trump era
The Republican Congress is Responsible
For political and moral reasons, it is important to remember that very little of what the President is now doing is possible without a compliant Congress. Executive orders in most cases fill in the blanks that legislation leaves to the President's discretion. So this isn't just a matter of the sway a Congress of the President's party can exercise over him, which is substantial. In many or most cases, Executive Orders and Actions can literally be overruled with new legislation.
