Final answer:
To remove a president from office through impeachment in the United States, a two-thirds majority in the Senate is required for conviction and removal.
Step-by-step explanation:
To remove a president from office in the United States, the process of impeachment must be followed. In the case of President Bill Clinton, he was impeached in the House of Representatives, but not removed from office. In the Senate trial, there was not enough support to reach the required two-thirds majority needed for conviction and removal. Therefore, Clinton remained in office despite being impeached.
