Final answer:
The House of Representatives has the sole power to impeach high-ranking government officials, including the President and Vice President. This is a key check on government power.
Step-by-step explanation:
The House of Representatives has the sole power of impeachment, which allows it to formally accuse the President, Vice President, and other federal officials of misconduct. This power is a critical component of the checks and balances designed to prevent abuse of power within the US government. The House's role in impeachment proceedings is likened to that of a prosecutor, bringing charges against a federal official, which will then be tried by the Senate.
