Andrew Johnson's drunken vice-presidential inaugural address

Andrew Johnson was purportedly drunk when he made his inaugural address as vice president of the United States on March 4, 1865. Multiple sources suggest Johnson had been under the influence for at least a week prior to the inauguration, that he drank heavily the night before the inauguration, and that he consumed either three glasses of whiskey or a glass of French brandy the morning of the ceremony.
