So why did Hillary forgive Bill? A new report claims to have the answer, along with other inside info on her reaction to his affair in the mid-90s.
The report is coming out of conservative website The Washington Free Beacon. According to CNN, the outlet says it's quoting the documents of Diane Blair, a deceased political science professor who was a close friend of Hillary's.
"[The affair] was a lapse, but [Hillary] says to his credit he tried to break it off, tried to pull away, tried to manage someone who was clearly a 'narcissistic loony toon'; but it was beyond control."
According to the Free Beacon, these quotes are coming from Blair's papers that were donated to the University of Arkansas in 2010 by her husband. She died in 2000.
Blair apparently said Hillary thought her husband's sex with Monica Lewinsky didn't have "any real meaning," and that she felt the former president might have had the affair due to the stress of their personal losses - her father and his mother, along with their friend Vince Foster, died after he took office.
The Free Beacon provides a lengthy assessment of the documents, dubbing Hillary Clinton both a "devoted mother" and a "cutthroat strategist."
Of course, the report comes as rumors build that Clinton will run for president in 2016 -- and as headlines build as to whether Bill Clinton and his past will help or hurt his wife's potential candidacy.

FILE - In this July 11, 2001, file photo, Monica Lewinsky arrives for a special screening of "The Score" in New York. Lewinsky says there's no question her boss, Bill Clinton, "took advantage" of her when he was president. But if there was any abuse in their affair, she says, it came afterward, when Clinton's inner circle tried to discredit her and his opponents used her as a pawn. The former White House intern, now 40, writes about her life in the next issue of Vanity Fair magazine, out in May 2014. In released excerpts, she says she's perhaps the first Internet scapegoat and wants to speak out on behalf of other victims of online humiliation.(AP Photo/Darla Khazei, File)
