The government is made so that no one person has any greater amount of unchecked power than the next, that's why congress exists, to run said checks, and that's why right now, congress is running the show with very bad outcomes.
People like to claim the use of Executive Orders should keep everything in check, but those orders are only effective if they can legally, and financially be carried out. It has been shown that congress can overturn executive orders (such as the Truman Order), or even cut off funding needed to carry out an executive order.
Furthermore, a veto can be overridden with a two-thirds majority vote in order to end said executive orders.
So, before anyone tries to say that the president is solely responsible for anything that goes on in the white house or what passes, just remember that Congress has all the cards in their hands.
