Federal prosecutors in the United States are to conduct a criminal investigation into the pardoning of a fugitive multi-millionaire businessman by the former president, Bill Clinton. The US Attorney in New York, Mary Jo White, says she will attempt to discover whether there was an illegal transfer of money to obtain the pardon. Two congressional committees are already conducting inquiries into the pardoning of the businessman, Marc Rich, who fled to Switzerland 17 years ago while facing more than 50 charges of tax evasion and illegal oil trading. It has already emerged, according to BBC, that Mr. Rich's former wife, Denise, was a major donor to the Democratic party and Hillary Clinton's successful campaign to be elected to the US Senate. Mrs. Rich is also known to have given at least $450,000 to the Clinton Presidential Library Fund. The pardon for Mr. Rich was one of 141 signed by Mr Clinton.
