Republican front-runner Donald Trump took a new shot against Hillary Clinton Saturday night, citing her husband Bill Clinton's history of unfaithfulness and sexual misconduct while in office and saying the former president has a "penchant for sexism," NBC News reported. The newest iteration in the increasingly personal war of words between the two presidential candidates took place on Twitter, as Trump reacted to the announcement of Bill Clinton campaigning for his wife.

The exact wording suggests that Trump was responding to comments Hillary Clinton made in an interview last week. The Democratic front-runner said in an interview last week that Trump has "a penchant for sexism" after the billionaire said she "got schlonged" in losing to Barack Obama in 2008, CNN reported.

"I don’t respond to him personally, because he thrives on that kind of exchange," she said in an interview with the Des Moines Register. “I think he has to answer for what he says, and I assume that others will make the larger point about his language. It’s not the first time he’s demonstrated a penchant for sexism. Again, I’m not sure anybody’s surprised that he keeps pushing the envelope.”

Trump blasted Clinton earlier this week, accusing her of playing "women being degraded card."

Trump told a laughing crowd at a campaign rally on Monday that Clinton "got schlonged" in the 2008 election, using language that was viewed as inappropriate for a presidential candidate, in addition to being widely criticized as sexist.

"Even her race to Obama [in 2008], she was gonna beat Obama," Trump said, according to TPM. "I don't know who would be worse, I don't know. How does it get worse? But she was gonna beat -- she was favored to win -- and she got schlonged. She lost."
