in what ways does congress carry out oversight
Congressional oversight Congressional oversight is oversight by the United States Congress over the Executive Branch, including the numerous U.S. federal agencies. Congressional oversight includes the review, monitoring, and supervision of federal agencies, programs, activities, and policy implementation.[1] Congress exercises this power largely through its congressional committee system. Oversight also occurs in a wide variety of congressional activities and contexts. These include authorization, appropriations, investigative, and legislative hearings by standing committees; specialized investigations by select committees; and reviews and studies by congressional support agencies and staff.
Impeachment in the United States 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."[3] The House of Representatives has the sole power of impeaching,[4] while the United States Senate has the sole power to try all impeachments.[5] 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 cannot review such proceedings.
