year. Hansen tried unsuccessfully to challenge the election result. Campaign finance law violations In 1974, Hansen became the first member of Congress to be convicted of violating a 1971 campaign finance law requiring disclosure of all financial contributions to his campaign. A federal judge found him guilty of not disclosing all his loans and profits, and sentenced him to pay a fine. Failure to File Income Tax Forms In October 1976, it was revealed by the Lewiston Morning Tribune that Hansen had failed to file his income tax returns for several years. The first instance was in the spring of 1969 when Hansen had a pending USDA appointment and a routine background check by the FBI had found the omission. The director of the IRS office in Boise was ordered by higher ups in the Treasury Department to open the office on a Saturday (May 3, 1969) so that Hansen could travel to Boise from Washington, D.C. to file the delinquent taxes for years 1966, 1967 and 1968 and pay what was owed. Hansen was also late filing for 1970, 1971, 1973 and 1975. A month later Hansen still managed to win reelection, although by the smallest margin in November 1976 among his many elections to Congress, until his defeat in 1984. Filing false disclosure statements In 1983, Hansen was indicted by a federal grand jury on four charges of filing false financial disclosure statements. He was accused of concealing more than $245,000 in loans and $87,000 in profits from silver speculation, much of it in his wife's name. Violation of Ethics Act In 1984 Hansen was convicted of violating the 1978 Ethics in Government Act. He had failed to disclose $334,000 in personal loans to his campaign. He was sentenced to six months in prison and fined $40,000. Appealing all the way to the US Supreme Court, his conviction was vacated and the fine returned to him. Bank fraud In 1992, Hansen was in prison again on charges of defrauding two Idaho banks and 100 individuals in a $30 million investment scheme. He was sentenced to four years in prison. Death In 2014, he died at a hospital in Pocatello, Idaho, aged 83. Election results Source: Books To harass our people: The IRS and government abuse of power, Positive Publications, (1981).
