It was The Day Reagan Was Shot.
In 1981, after the March 30 assassination attempt on Reagan, Haig asserted before reporters "I am in control here" as a result of Reagan's hospitalization. Constitutionally, gentlemen, you have the President, the Vice President and the Secretary of State in that order, and should the President decide he wants to transfer the helm to the Vice President, he will do so. He has not done that. As of now, I am in control here, in the White House, pending return of the Vice President and in close touch with him. If something came up, I would check with him, of course.
