Clinton, the Democratic presidential nominee, "won't control the border, she won't stop [the Islamic State in Iraq and Syria], she won't even call our enemy by its name, she won't maintain law and order, she won't fight for the Constitution, and she won't bring jobs back to struggling Americans," Trump said in an email to supporters on Tuesday.

Trump added he won the GOP primary by focusing on issues that "NO ONE else dared to touch."

ADVERTISEMENT Trump denied during a phone interview on Fox Business on Tuesday morning said he does not plan on changing his campaign strategy, despite his recent bout of poor polling.

“I think that my temperament has gotten me here,” Trump said. "I certainly don't think it's appropriate to start changing all of a sudden when you've been winning."

Trump on Monday outlined his tax plan and blasted international trade deals during a carefully scripted speech at the Detroit Economic Club.

Clinton has a speech planned for Thursday to counter Trump's, which came on the heels of several days of negative attention.

The Republican National Committee on Tuesday released a memo attacking Clinton's economic policies a day after Trump's own economic address.
