PRESCOTT VALLEY, Ariz. - Donald Trump played his greatest hits in Prescott Valley Tuesday.

"We are going to build the wall, believe me," he said before the crowd roared.

He also sought to defuse what Hillary Clinton has slammed as one of his biggest misses -- his sometimes checkered business past.

"What kind of a genius loses a billion dollars in a single year?" Clinton asked earlier in the campaign.

RECAP: Trump holds rally in Prescott Valley

Trump stuck to an hour-long speech in the teleprompter and tried to put Clinton on the defensive.

"Her donors and contributors have used the same tax laws as I did," he said.

He delivered a new attack on Hillary and Bill Clinton after the former president ripped Obamacare as a crazy system.

"In the meantime she wants to double down on Obamacare," Trump said. "I'll bet (Bill Clinton) went through hell last night."

He parlayed that into a comment on Clinton's marriage, saying "honestly, there have been many nights when he's gone through hell with Hillary."

Polls show Trump and Clinton in a toss-up race for Arizona's vote, but the Republican nominee was preaching to the converted at the rally. Yavapai County Republicans are the most dependable voters in Arizona.
