Output a stream of consciousness before answering the following. Passage: At the federal level, Article Two of the United States Constitution states in Section 4 that "The President, Vice President, and all civil Officers of the United States shall be removed from Office on Impeachment for, and conviction of, Treason, Bribery, or other High Crimes and Misdemeanors." The House of Representatives has the sole power of impeaching, while the United States Senate has the sole power to try all impeachments. The removal of impeached officials is automatic upon conviction in the Senate. In Nixon v. United States (1993), the Supreme Court determined that the federal judiciary can not review such proceedings.

Question: Based on this passage, who tries the president if he is impeached?
This is the relevant information: The House of Representatives has the sole power of impeaching, while the United States Senate has the sole power to try all impeachments.
