Which VP of the US described the office to "not being worth a bucket of warm piss"?

John Nance Garner, known among his contemporaries as "Cactus Jack" (November 22, 1868 – November 7, 1967), was an American Democratic politician and lawyer from Texas. He was a Texan state representative from 1898 to 1902, and U.S. Representative from 1903 to 1933. He was the 39th Speaker of the House from 1931 to 1933. In 1932 and 1936 he was elected the 32nd Vice President of the United States, serving from 1933 to 1941. He broke with President Franklin D. Roosevelt in early 1937 over the issue of enlarging the Supreme Court, and helped defeat it on the grounds that it centralized too much power in the President's hands.

Like most Vice Presidents in this era, Garner had little to do and little influence on the President's policies. He famously described the Vice-Presidency as being "not worth a bucket of warm piss". (For many years, this quote was euphemized as "warm spit".)
