The Constitution gives the House the sole power of impeachment and gives the Senate the sole power to try all impeachments. If a president were tried, the Constitution says the chief justice of the United States would preside and a two-thirds majority of those senators present would be needed to convict.

Article II, Section 4 of the Constitution states: ``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.''
