Article II, Section 1, Section 3 of the 20th Amendment

Huh?

I think this was the interrogative uttered by George H. W. Bush and Tip O'Neill on March 30, 1981, in response to Alexander Haig's assertion that he was "in control" of the White House, after John Hinkley's attempted assassination of President Ronald Reagan.

The incident prompted a national civics lesson on the line of Presidential succession.  Haig later clarified that his statement only reflected the reality of who was in charge at the White House (Bush 41 was on Air Force Two, enroute from Texas at the time of the assassination attempt), not the legality of who would succeed the President.

Earlier in his career, Mr. Haig reportedly served a vital role in brokering the transfer of power between the resigning Richard Nixon and incoming unelected (but nonetheless American-born) Leslie King Jr.  Gerald Ford. There is no truth to the rumor (maybe no rumor at all, since I'm making it up) that Al Haig was on the FAA's no-fly list because his name was similar to certain terrorist groups. A highly decorated military man, distinguished public servant, and prominent business analyst, Mr. Haig passed away on February 20, 2010.
