Hillary Clinton says the 'gutsiest' decision she has ever made was to remain married to Bill Clinton during his highly-publicized cheating scandal.

'I think the gutsiest thing I've ever done - well, personally - was make the decision to stay in my marriage,' the former First Lady said on Good Morning America Tuesday.

'Publicly, politically - run for president and keep going. Just get up every day and keep going,' the 71-year-old former presidential candidate added.

The admission shocked daughter Chelsea Clinton who was seated next to her mother for a joint interview promoting their new book: The Book of Gutsy Women: Favorite Stories of Courage and Resilience.

'Oh, goodness. I think I'm so overwhelmed by my mother's answer that I'm a bit out of words. I'm so proud to be her daughter,' Chelsea said.

Asked the gutsiest thing she's ever done, Hillary Clinton tells @GMA, "Personally, make the decision to stay in my marriage."

The cheating scandal involving then-President Bill Clinton and 22-year-old White House intern Monica Lewinsky rocked the nation, led to impeachment and left a scorned wife.

At the time, Hillary remained supportive of her husband, standing by his side and denying the allegations against him.

And this isn't the first time she's given insight into her feelings on her husband's infidelities.

In her 2017 book, What Happened, Hillary shed light on scandal.

'There were times that I was deeply unsure about whether our marriage could or should survive,' she writes without specifically mentioning the affair.

'But on those days I asked myself the question that mattered most to me: Do I still love him? And can I still be in this marriage without becoming unrecognizable to myself-twisted by anger, resentment, or remoteness. The answers were always yes. So I kept going.'

During Tuesday's interview, the former Secretary of State spoke on the impeachment inquiry of President Trump and said the Democrats should tread with caution.

'I think the evidence concerning Ukraine is so dramatic and irrefutable because it came right out of the White House,' she said. 'So let the impeachment inquiry proceed.

'I know that they will do a thoughtful, thorough job. Nobody should jump to any conclusions.'

The former presidential candidate added that she has not been questioned over her email records sent to her private email server, despite the Trump Administration pushing for an investigation.

'I think it's an unfortunate diversion,' Hillary said. 'You go and you talk to people who've been experienced diplomats for many years, and then you retroactively classify what they said 10 years ago? I think it's really a shame that they're doing that, and hopefully people will not be distracted.'

The answer shocked Chelsea, who said she was 'overwhelmed' and 'out of words' but added that she's 'proud to be her daughter'

ALL THE REASONS HILLARY COULD HAVE LEFT BILL In 1998, Kathleen Willey alleged Bill Clinton groped her without consent in the White House Oval Office in 1993. Six of Willey's friends testified under oath that she and Bill had a consensual relationship. In 1992, news reporter Gennifer Flowers claimed that she and then-presidential candidate Bill Clinton carried on a 12-year long affair. Bill and Hillary were married for 17 years at the time. Bill denied the affair in a now-famous interview with his wife on 60 Minutes. In the 60 Minutes interview, Hillary emphatically supported her husband, which saved his candidacy but may have cost her her career. The 1998 Monica Lewinsky scandal put Bill's infidelities at the forefront, which were an embarrassment to the entire Clinton family - especially his wife. And despite finally admitting to having 'sexual relations' with the White House intern, Hillary stood by her husband. The former president reportedly cheated on his wife on numerous occasions and didn't stop after he was nearly impeached. Secret Service Agent Bill Kessler claimed in his book, The First Family Detail, that a woman named Julie McMahon was having an affair with Bill, though those reports were never confirmed. In a 1999 episode of Dateline, former Bill Clinton volunteer Juanita Broaddrick claimed that in the late 1970s, Clinton raped her in her hotel room. Clinton denied Broaddrick's allegations through his lawyer. In October 2016, Leslie Millwee accused Bill Clinton of sexually assaulting her three times in 1980. Advertisement

She also touched on how the impeachment inquiry could potentially impact the 2020 presidential election.

'I don't know [the impact on the election] yet. But I think there was no choice,' she said. 'Speaker Pelosi was reluctant as we all know, but what I hope the Democrats will do is not only proceed in a very deliberative way on the impeachment inquiry but tell the American people what they've accomplished.

'They've passed legislation on gun safety, improving health, lowering prescription drug costs, doing so many things that the American people really want and need and it goes to the Senate and dies. So I think the Democrats have to go on two tracks here, but they will do that.'

Hillary and Chelsea Clinton have been busy promoting their latest book, appearing on The Late Show with Stephen Colbert Monday night and CBS This Morning on Sunday.

In their Colbert interview, Hillary condemned Secretary of State Mike Pompeo for not intervening on the phone call between Donald Trump and the Ukrainian President.

'I think if the Secretary of State was on the call, as is now being reported, he should have been one of the very first people to just say 'Wait a minute, we've got to clean this up, you can't let that stand,' but we don't know what he did.'

Colbert asked Clinton: 'How many times when you were secretary of state did you have to say to Obama, ''You can't extort foreign countries to get dirt on your political enemies?''

She laughed at the question before responding: 'Yeah, that never happened.'

Clinton recalled the duties of the Secretary of State, having previously served in the role from 2009 until 2013, during Obama's first term. She explained that in the build up to a call with the leader of a foreign nation several heads of department typically bring up talking points.

'I'm not sure they've even given up on trying to give him any sorts of preparation because they don't know what he's going to say,' Clinton added about Trump.
