Why did Vice President Spiro T. Agnew resign?
He resigned on October 10, 1973, as a result of criminal
investigations dating from his term as the Governor of Maryland
(January, 1967 - January, 1969). He later pled "no contest" to
bribery charges and was disbarred.
After being forced to resign as Vice President, his party did
not consider him to be a viable candidate for President.
