The legislative branch can `` check ‘’ the executive branch by rejecting the President`s veto of a legislative action …this is known as an override . A two third vote in each legislative chamber ( House of Representatives and Senate ) is required to override a Presidential veto .
The Senate can reject a treaty that the Executive has signed ; a two thirds vote in the Senate is required to formally enact a treaty .
The Senate must approve Executive appointments to cabinet , and the Federal Judiciary .
The ultimate check for the legislative branch is the power to impeach and remove the president . The House of Representatives acts as prosecutor , and The Senate acts as jury . The House of Representatives drafted articles of impeachment against President Richard Nixon in 1974 , but Nixon resigned the office of the presidency before he was formally impeached .
