The feud between Republican frontrunner Donald Trump and Democratic frontrunner Hillary Clinton hit a boiling point over the weekend when the former first lady accused the billionaire of sexism. Trump took to Twitter to slam Bill Clinton for his former sex scandals and had a "penchant for sexism."

Hillary Clinton has announced that she is letting her husband out to campaign but HE'S DEMONSTRATED A PENCHANT FOR SEXISM, so inappropriate! — Donald J. Trump (@realDonaldTrump) December 27, 2015

While everyone knows about Monica Lewinsky, the White House intern who was in love with Bill and regularly performed oral sex on him, most millennials give the former president a pass. After all it consensual between two adults, and Hillary forgave him- to quote Whitney Houston, "It's not right but it's okay."

Lewinsky was not the only one. Bill's sexual encounters stretched back throughout his entire political career -- which predates the first millennial being born and included cases of sexual misconduct, harassment, assault, and even an accusation of rape. Unlike the Duke Lacrosse Players or Mattress Girl, these stories had validity but didn't get much mainstream attention.

Here's a run down:

Eileen Wellstone allegedly was sexually assaulted by a 23-year old Bill Clinton at a pub near Oxford University (the future president was a student there). He admitted to the encounter, but claimed it was consensual. Nonetheless, he ended up leaving the school a year after the incident without a degree.

According to Capitol Hill Blue, just three years later while he was dating Hillary at Yale University, a female student called campus police stating that Bill sexually molested her.

In 1974, an unnamed University of Arkansas student complained to her faculty advisor that her law professor Bill Clinton groped her and forced his hand inside her blouse. The 28-year-old law professor claimed that she was the one who came onto him.

Capitol Hill Blue reported that "several former students at the University have confirmed the incident in confidential interviews and said there were other reports of Clinton attempting to force himself on female students."

Clinton was elected Attorney General of Arkansas in 1977, soon afterward a young woman lawyer in Little Rock claimed that she was assaulted by him -- he forced himself on her, biting and bruising the woman, wrote Roger Morris in Partners in Power.

A year later, Juanita Broaddrick claimed that Bill raped her when she was a volunteer on his campaign for governor while she was at a nursing student conference in Little Rock. She claimed that he forced himself on her while she screamed "please stop," and he bit her lip. Norma Rodgers, a friend who was sharing a hotel room with Broaddrick during the conference, confirmed her claims that she had been sexually assaulted.

Broaddrick did not come forward with the claims for two decades, claiming she was intimidated and ashamed.

Bill also had a consensual relationship with Regina Hopper Blakely and Robyn Dickey in the late 70's, according to L.D. Brown, a former Arkansas state trooper who guarded Clinton.

In 1979, Carolyn Moffet was a legal secretary in Little Rock who was invited to Bill's hotel room after a fundraiser. When she got there, she discovered the future president sitting on a couch only wearing a t-shirt.

"When I went in, he was sitting on a couch, wearing only an undershirt. He pointed at his penis and told me to suck it. I told him I didn’t even do that for my boyfriend, and he got mad, grabbed my head and shoved it into his lap. I pulled away from him and ran out of the room," Moffet said.

After he became governor in 1979, he began to have a 12-year affair with Gennifer Flowers. She was an actress and model, who taped phone interviews that she had with Clinton. In his 2004 autobiography, Bill admitted to a sexual encounter with Flowers, but said it happened just once in 1977.

It was alleged by Brown that he had an affair with Lencola Sullivan, who was Miss Arkansas in 1980.

Bill was a big fan of beauty queens, he bedded two other Miss Arkansas winners, Elizabeth Ward and Sally Perdue in 1982 and 1983. Ward claimed in 1982 that she was forcibly raped by the governor, but recanted those statements in 1998. Ward announced she did have sex with Bill, but it was consensual. Perdue said that she was threatened not to reveal her affair by several Democratic Party staff members .

"They knew that I went jogging by myself and he couldn't guarantee what would happen to my pretty little legs," Perdue said to the Village Voice about the threat.

In 1984, rock'n'roll groupie Connie Hamzy claimed she was propositioned by then-Governor Clinton who said he wanted to bring her to his hotel room. Clinton denied these claims saying that Hamzy came onto him and showed him her breasts.

Bill also had an alleged longtime affair with Dolly Kyle Browning throughout the mid-1970's all the way until he became president. She said that when she tried to write a book about the affair Bill did everything he could to stop her. She ended up suing him for damages, but the U.S. Court of Appeals denied her appeal.

On the eve of his run for the presidency, Bill sexually harassed Arkansas state worker Paula Jones in a hotel room where he flashed himself and demanded oral sex. Jones sued the former president and received an $850,000 cash settlement over the matter. Bill still denies he ever had a sexual encounter with Jones.

That was a busy year for Clinton. According to Capitol Hill Blue, he allegedly pinned political fundraiser Sandra Allen James against a wall and stuck his hands up her dress. She screamed so loud that the Arkansas State Police knocked on the hotel door and asked if everything was okay. When she told her Democratic fundraising boss about the incident, he told her to "keep your mouth shut."

During the '92 campaign for president, airline stewardess Christy Zercher alleged that the 46-year old presidential candidate fondled her on a plane flight, while Hillary slept just a few feet away.

After he was elected president, Bill was accused again of molesting another volunteer, Kathleen Willey. She claimed that the president grabbed her, fondled her breast, and pressed her hand against his genitals during an Oval Office meeting.



Then there was Monica Lewinsky, enough said.

These days, most of Clinton's affairs are on the kept out of the media -- no new girls have come forward, though several secret service members have claimed that Bill has a mistress with the code name "The Energizer Bunny."

Earlier this year, the former president's sex life came under scrutiny again when it was revealed that Bill had flown with billionaire Jeffery Epstein at least 10 times on the "Lolita Express" -- his jet that was used to pick up underage prostitutes. Epstein pleaded guilty to the charges of pedophilia in late 2007.

When asked about those trips with the former president, Epstein pleaded the Fifth.
