Bill Clinton has faced interrogation over his handling of the Monica Lewinsky scandal, after saying he supports the #MeToo anti-abuse movement.

In an interview with NBC's Today Show released yesterday, Clinton bristled at questions over whether he should have resigned 20 years ago over his sexual relationship with the White House intern and whether the #MeToo movement has changed his perspective.

At the same time, the former Democratic president claimed credit for empowering women in his orbit and disputed that he might owe Lewinsky a private apology, insisting his public televised apology was adequate.

US correspondent Steve Merczynski told Greg Boyed Clinton was clearly under pressure.

"He didn't seem prepared to answer these questions. This story from 20 years ago was going to be talked on during his book tour."

Clinton is promoting his new fictional thriller, The President Is Missing, with best-selling author James Patterson.

In clips released from the interview, Clinton was at times both vague and combative in his answers, repeatedly blaming his critics and even the NBC interviewer for "omitting facts" by trying to lump him in with other men who have abused their positions of power to leverage sexual relationships.

"I dealt with it 20 years ago, plus," said Clinton. "And the American people, two-thirds of them stayed with me. And I've tried to do a good job since then, and with my life and with my work. That's all I have to say."

Clinton said he was right not to resign. And while he said he supports the #MeToo movement, "I still have questions about some of the decisions which have been made."

Clinton said he doesn't think President Donald Trump has gotten a free pass, but that Trump's alleged exploits haven't "gotten anything like the coverage you would expect." Trump has been accused by more than a dozen women of sexual misconduct and was caught on tape bragging about grabbing women's crotches.

On any parallels between the two presidents, Clinton said: "A lot of the facts have been conveniently omitted to make the story work, I think partly because (Trump's supporters) are frustrated that they got all these serious allegations against the current occupant in the Oval Office. And his donors don't seem to care."

On not resigning, Clinton said: "I think I did the right thing. I defended the Constitution."

Patterson joined Clinton for the NBC interview, and seemed equally surprised that Clinton would be asked about the Lewinsky scandal on his book tour. At one point, Patterson noted that other presidents, John F. Kennedy and Lyndon B. Johnson, also were suspected of having extramarital affairs and that it was in the past.
