Donald Trump took a swipe at Hillary Clinton with a jibe about her husband late Saturday, the latest in a war of words between the two presidential hopefuls.
The Republican frontrunner sparked a firestorm last week for calling Clinton's debate bathroom break "disgusting" and for saying she had been "schlonged" in the 2008 Democratic primary.
While Clinton wouldn't respond directly to the remarks, she told the Des Moines Register she deplored the "tone" of Trump's campaign and said he had shown a "penchant for sexism."

Trump has since defended his use of the term "schlonged" and struck out against allegations of sexism.
In one Tweet following Clinton's interview Trump warned her to "be careful" when complaining about sexism -- and late Saturday he fired another salvo with a dig about her husband, Bill Clinton.
"Hillary Clinton has announced that she is letting her husband out to campaign but HE'S DEMONSTRATED A PENCHANT FOR SEXISM, so inappropriate," he said on Twitter.
There was no immediate response from Bill Clinton or Hillary Clinton's campaign. Hillary Clinton announced last week that she would be bringing her husband on the campaign trail, calling him a "secret weapon."
