6. Spiro Agnew
Spiro Agnew, the number 6 on our list of most corrupt politicians in US history was a Republican who served as Vice President from January 1969 until October 1973 under President Richard Nixon. In October, Spiro Agnew resigned due to unrelated issues to the Watergate scandal. Agnew was the second vice president of the United States to resign; the first was John Calhoun who left back in 1832. When President Nixon won the re-elections, the U.S. Attorney investigation targeted Spiro Agnew for bribery, tax fraud, extortion and conspiracy that was related to his political career in Maryland. Agnew was charged with accepting bribes of more than $100,000, but after that, he decided not to face trial and to resign, he got three years on probation and was fined $10,000. However, when later, in 1981 the civil court found out that Spiro Agnew accepted $147,000 in bribes while he was a governor of Maryland and he received $17,500 while he was a vice president, he had to reimburse the state $268,000.
