The US Constitution limits the power of the executive branch through  Congress and the Supreme Court.

The Constitution of the United States used the principle known as "Separation of Powers" to provide a check and balance between coequal branches of government.  The Executive Branch (President), the Legislative Branch (Congress), and the Judicial Branch (the courts, headed by the Supreme Court) are the three branches of government.

The "Separation of Powers" principle was an idea embedded into the plans for American government by our founding fathers, based on their reading of Enlightenment political theory.  The terminology "separation of powers" was introduced by Charles-Louis de Secondat, the Baron of Montesquieu.  (Usually he's referred to as just "Montesquieu.")  He wrote an important work of political theory called The Spirit of the Laws, published in 1748.  Within his treatment of how governments will function best, Montesquieu argued that executive, legislative, and judicial functions of government ought to be divided between parts of the government, so that no one person or division of the government can infringe on the overall rights of others in the government or of the members of the society overall.
