Former United States Secret Service uniformed officer Gary Byrne has released a new book about his experiences at the White House, adding new controversy to former U.S. President Bill Clinton's personal history with other women.

Gary Bryne, in his book titled Crisis of Character: A White House Secret Service Officer Discloses His Firsthand Experience with Hillary, Bill, and How They Operate, argues that Clinton had a love affair with former U.S. Vice President Walter Mondale's daughter, Eleanor Mondale.

According to the private broadcaster NTV's website, Bryne argues that during his presidency Clinton had a love affair with Eleanor in the Oval Office, in addition to the affair he had with Monica Lewinsky.

Bryne adds that Clinton and Eleanor a former broadcast reporter, would have secret meetings in the Oval Office during the times when the former president was dealing with the sex scandal with Lewinsky.

There has been no comments made from the Clinton family. However, such controversy is expected to have an effect on the Democratic presidential hopeful Hillary Clinton's election campaign against her biggest rival, the Republican candidate Donald Trump.

Hillary Clinton's spokesperson said that the claim was just a made up story.

Eleanor has previously had relationships with Hollywood stars such as Arnold Schwarzenegger, James Belushi, multi-billionaire Ron Perelman, and rock star Don Herley, NTV's report added.
