The President, or the "Executive Branch", as its called, proposes laws - which Congress (the "Legislative Branch") then can either act on or ignore. Its the Supreme Court (the "Judicial Branch") that acts to 'check' the powers of Congress, by the ability to overturn laws that are unconstitutional. The President nominates Supreme Court justices, who then have to be approved by the Senate, so its a big circular power exchange.... The Executive Branch has a number of ways to control the powers of Congress. There is the Presidential veto. There is the appointment of judges and other Federal officers.
Congress can override presidential vetoes by a 2/3 vote and so pass legislation against the president's wishes. The Senate must approve the president's nominations for federal judges , cabinet and other high-ranking positions. Congress also controls the money- the president can send troops somewhere, but only Congress can give him the money to keep them there for any length of time.
Congress also has the power to remove the President from office if he fails to do his job.
