Impeachment of President requires a qualified House resolution, investigation by the other House, and removal if sustained. Impeachment is initiated by either House on a charge of constitutional violation, after prescribed written notice and support by at least one quarter of the initiating House and passage of the initiating resolution by a qualified supermajority. The other House must investigate with the President entitled to appear and be represented; if that House, by a qualified supermajority, declares the charge sustained, the President is removed from office from the date of that resolution.
