As the White House played down the weekend revelations about Mrs Hillary Clinton's dealings with a New Age psychic adviser, another new book alleges President Clinton was a CIA informer as a student.
The book, Partners in Power the Clintons and Their America, claims the CIA connection continued into Mr Clinton's period as Governor of Arkansas.
There are also details about the drug peddling activities of his step brother, Roger, who served a reduced two year sentence in the 1980s.
The White House refused to respond to specific allegations about Mr Clinton, but his associate legal counsel, Mr Mark Fabiani, said through a spokesman that they were "bizarre and speak for themselves". The CIA said it has a long standing policy not to comment on allegations of affiliation with the agency.
The author, Roger Morris, is a history professor at the University of New Mexico, and a former foreign service officer and national security aide to President Johnson and President Nixon. He resigned from the foreign service in protest against the Vietnam War and later wrote a highly acclaimed biography of Nixon.
He predicts that like Nixon Mr Clinton will be re-elected but later forced to resign in disgrace as the investigations by the Special Counsel, Mr Kenneth Starr, delve more deeply into Whitewater matters and the White House abuse of confidential FBI files.
Mr Morris says in his book that while several CIA officers he knows do not believe that Mr Clinton became an agency "asset" during the Vietnam era, others whom he believes to be "more plausible" say he was.
His chief source made a record of Mr Clinton's listing within the CIA as an informant for "Operation Chaos" in the late 1960s. The CIA purged these files in the 1970s when the Senate Foreign Relations Committee investigated the agency's spying activities.
Mr Morris writes that Operation Chaos aimed at uncovering any foreign hand in anti Vietnam War activities at home or abroad to the point of recruiting American student informants and placing provocateurs among the demonstrators.
Mr Clinton was used in this way, the book alleges, when he was a Rhodes Scholar at Oxford and when he travelled to Moscow at Christmas, 1969.
On the face of it, these charges are bizarre. Mr Clinton actually used his spell at Oxford to avoid being drafted to fight in Vietnam. But another of Mr Morris's CIA sources says that being an informant was a "further insurance against the draft".
The revelations about Mrs Clinton's sessions with a New Age "spiritual" adviser, Ms Jean Houston, in the new book by Bob Woodward, The Choice, have been widely reported in the media which seem to not know how seriously to take them.
The White House spokesman, Mr Mike McCurry, rejects the term "seances" for these sessions, in which Mrs Clinton held two way conversations with Eleanor Roosevek and Mahatzna Gandhi.
Mrs Clinton yesterday jokingly told an audience she was addressing in Nashville that she had "cleared it with Eleanor Roosevelt".
The US Supreme Court has agreed to hear Mr Clinton's request to delay the sexual harassment suit by a former Arkansas state employee, Ms Paula Jones, until he leaves office.
