The Executive Branch is responsible for either signing a bill into law or rejecting (vetoing) it, in which case the house must reach a 2/3r'd's majority to force it into law.
The only thing the president can do about creating laws is either veto it and he can grant pardons. It the legislatures job to create laws and pass them and what not.
The executive branch, led by the President, plays a vital role in creating laws by proposing legislation, signing or vetoing bills passed by Congress, and enforcing laws. If a President vetoes a bill, Congress can override this veto with a two-thirds majority vote. The executive branch evaluates laws for their effectiveness and may suggest changes to Congress.
