What US vice president referred to his critics as "nattering nabobs of negativism"?

Spiro Theodore Agnew (9 November 1918 – 17 September 1996) Thirty-ninth Vice President of the United States, under President Richard Nixon; was born Spiro Anagnostopoulos. He was quoted as saying, "In the United States today, we have more than our share of the nattering nabobs of negativism."

Agnew was born in Baltimore, Maryland, to an American mother and a Greek immigrant father. He graduated from Johns Hopkins University and the University of Baltimore School of Law, and was then drafted into the United States Army in 1941. Agnew served as an officer during the Second World War and later being recalled for service during the Korean War in 1950. He was appointed to the Baltimore County Board of Zoning Appeals in 1957. In 1960, he lost an election for the Baltimore City Circuit Court, but in 1962 was elected Baltimore County Executive. In 1966, Agnew was elected the 55th Governor of Maryland. He was the first Greek-American to hold the position, serving between 1967 and 1969.

Agnew was often characterized as Nixon's "hatchet man" when defending the administration on the Vietnam War. Agnew was chosen to make several speeches in which he spoke out against anti-war protesters and the media portrayal of the Vietnam War, labeling them "Un-American". However, he also spoke publicly against the actions of the Ohio Army National Guard that led to the Kent State shootings in 1970, even describing their action as "murder".
