Impeachment of a federal official requires a trial conducted by the U.S. Senate. Although the Senate conducts the trial, the actual act of impeachment must be done through the U.S. House of Representatives by passing articles of impeachment.
The impeachment process begins in the House Judicial Committee who prepares the charges, or articles of impeachment. These are then voted upon, and if passed by a majority, move to the full House for voting. To go to trial, the full House must make a majority vote in favor of impeachment; then the process passes to the Senate. If the Senate convicts with a two-thirds vote, then Executive branch personnel are removed from office. For other federal positions, the Senate can choose to do nothing, remove the individual from office, and prevent him from holding any further offices.
