The three powers assigned exclusively to the House of Representatives are:
-
Initiate revenue bills - The Constitution specifies that all bills for raising revenue must originate in the House of Representatives.
-
Elect the President in the event of an Electoral College tie - If no candidate receives a majority of the electoral votes, the House of Representatives elects the President, with each state delegation casting one vote.
-
Impeach federal officials - The House has the sole authority to impeach federal officials, which is essentially bringing charges against them.
The other options listed (ratifying treaties, confirming presidential appointments, and trying cases of impeachment) are powers assigned to the Senate.
