And FYI, OP, that's only if he's convicted. The House of Representatives can vote (by simple majority) to impeach, but all that means is that the Senate has to hold a trial (with the Chief Justice of the Supreme Court presiding in lieu of the Vice President in this case, since a VP would have a conflict of interest in such a trial), and two-thirds of senators must vote "guilty" in order to convict (note that there is currently a Republican majority in the Senate).
Two presidents have been impeached in the past (Andrew Johnson and Bill Clinton), but neither was convicted by the Senate. Johnson was acquitted by a single vote (35–19), while in Clinton's case the votes to convict were shy of even a simple majority (50-50 on the charge of perjury, and 45-55 on obstruction of justice). There have been articles of impeachment which did not pass the House introduced against several others: Tyler (uniquely, by members of his own party), Truman, Nixon, and George W. Bush. Only in In Tyler's case did it even reach a floor vote (failing 83-127). Nixon avoided an impending vote by resigning, while the resolutions against Truman and Bush were deliberately buried in committee by House leadership.
