The Hillary Clinton Presidential campaign is spreading information that former President Bill Clinton may be utilized by his wife in a government position if she wins the White House.
However, under the 1964 Nepotism Law, passed after Robert Kennedy left the government to run for the US Senate, it is illegal for a relative of any President to be in a public, paid position in the government. It is seen as a conflict of interest, so for instance, Jeb Bush, after leaving the Governorship of Florida in 2007, was not eligible to serve in the administration of his brother, George W. Bush.
RFK was Attorney General under his brother, President John F. Kennedy, but the Congress decided after the Kennedy Administration’s end, that such a situation should not happen again. Also, JFK’s brother in law, R. Sargent Shriver, served as head of the Peace Corps.
So Bill Clinton could be an unpaid advisor, but cannot go on the government payroll, even assuming he would agree to donate any government paycheck to charity, as RFK did under his brother.
It is clearly assumed that Bill Clinton would have an important background role, but again, it cannot be as a cabinet officer or an official part of the White House staff, unless Congress agrees to change the law, but that is highly unlikely in the present political climate, with a Republican Congress, and the likelihood that at least the House of Representatives will remain Republican after this year’s Presidential and Congressional elections!
