S. Senate. .
The Congress also controls the president through the "power of the purse" > all appropriations would be legislated by Congress and not the president. .
Finally the ultimate power lies in the constitutional authority the Congress has to remove the president from office. This is a two stage process. First the U.S. House of Representatives (specifically the Judicial Committee) holds hearings and gathers evidence then turns over everything to the full House for a vote > a majority vote of the full House is required to impeach (or indict) the president. Second, the U.S. Senate holds a trial with the Chief Justice of the U.S. Supreme Court presiding. It requires a 2/3-majority vote of the full Senate to remove the president. Since the beginning, the U.S. House has impeached (indicted) two presidents > Andrew Johnson (1868) and Bill Clinton (1998) [Richard Nixon was almost impeached (1974), but resigned before the vote was taken]. The U.S. Senate has, to date, never removed a president from office.
Another problem the framers faced regarding the office of the presidency was the issue of terms of office. While they discussed limiting the terms, they elected to set the term of office at four years, and presidents would be indefinitely eligible to succeed themselves (in other words, presidents could stay in office as long as they could get reelected. George Washington established the informal tradition of serving two terms and then voluntarily stepping down. This tradition was followed until F D R served an unprecedented third (then a fourth) term of office (F D R died in office in 1945). Now there was a concern that F D R had started a new tradition > Congress moved quickly to stop this. In 1951, Congress proposed and the states ratified the 22nd Amendment > limiting the president to serving two terms. .
In regards to the powers of the president, the framers deliberately outlined them in broad terms.
