Hillary Clinton acknowledged that her husband's seedy sexual history is 'fair game' as she seeks the White House, but warned Republicans that those attacks don't stick.

'Didn't work before. It won't work again,' Clinton said today during an interview with John Dickerson on Face the Nation.

Dickerson wanted to get reaction from the former secretary of state on how she felt about Donald Trump putting out an Instagram video featuring Bill Clinton with White House intern and mistress Monica Lewinsky.

Hilary Clinton said, yes, her husband's sex scandals from the '90s are 'fair game,' but she warned Republicans today on Face the Nation that those attacks haven't worked

Face the Nation host John Dickerson wanted to get Hillary Clinton's reaction to a video Donald Trump put out that showed Bill Clinton with Monica Lewinsky

Trump was reacting to Hillary Clinton's claim that he was a sexist.

'Well, if he wants to engage in personal attacks from the past, that's his prerogative,' Clinton said. 'You know, so be it.'

Clinton than segued into promoting women-friendly policies like equal pay and a higher minimum wage.

'Which affects two-thirds of the women, who are the ones receiving the minimum wage,' the Democratic frontrunner explained.

She also touted an endorsement she's receiving today in New Hampshire from the Planned Parenthood Action Fund, the political arm of the reproductive health services provider, which performs abortions.

Trump, Clinton blasted, supports sucking federal funds away from Planned Parenthood.

'He can say whatever he wants about me,' she said. 'Let the voters judge that, but I am not going to let him or any of the other Republicans rip away the progress that women have made.'

Dickerson segued back to Bill Clinton's previous sex scandals, asking the candidate if she believed they were fair game.

She answered in the affirmative.

'Well, it's been fair game going back to the Republicans for some years,' she said. 'They can do it again if they want to. That can be their choice as to how to run in this campaign.'

Clinton said she didn't think the attacks would move the dial much.

'I think it's a dead end, blind alley for them,' she noted.

But, then again, she said, she 'can't run anybody else's campaign.'

Dickerson used the former secretary of state's words to end the segment.
