Donald Trump and Hillary Clinton continue to exchange harsh words on the campaign trail. The presumptive Republican nominee is critcizing his rival amid word she won't face criminal charges for use of a private email server. Josh Robin filed the following report.

Donald Trump on Hillary Clinton:

"We say Lie. Lie. Lie. Lie. Lie. Lie!" Trump said. "Dirty rotten liar!"

Hillary Clinton on Donald Trump:

"Donald Trump is temperamentally unfit to be president of the United States," Clinton said.

Trump spoke in the swing state of Ohio with potential running mate Newt Gingrich, the former House speaker whose chances of being Trump's running mate are increasing with other prominent Republicans turning Trump down.

Also drawing notice was Trump's long defense of a tweet found to have been lifted from a white supremacist website. Many thought it looked like a Jewish star. Trump says it's just a star.

"'Oh, but there is money behind it.' So actually, they're racially profiling. They're profiling, not us," Trump said.

Hours before, Trump's Jewish son-in-law wrote an extraordinary defense, saying the tweet may have been careless, but Trump is no anti-Semite.

Trump wasn't done giving some Republicans heartburn. A day after again defending Saddam Hussein, Trump doubled down.

"Saddam Hussein is a bad guy. But, he did one thing well. He killed terrorists," Trump said.

Left unspoken was Saddam's sponsorship of terrorism.

As for Clinton, she spoke under the faded marquis of one of Trump's shuttered casinos. The message: after four trips to bankruptcy court, Trump will bankrupt America, too.

"What he did for his businesses, and his workers, is nothing to brag about," she said.

Clinton then turned to Trump supporter Chris Christie.

"And if your governor would start doing his job instead of following Donald Trump around, holding his coat," she said.

Clinton didn't address her email, no doubt hoping the issue fades. But House Republicans plan to call at least two hearings, the first with the FBI director, then another with the U.S. attorney general, Loretta Lynch. Republicans are certainly eager for the issue to linger.
