Trump: I will appoint special prosecutor to investigate Clinton Foundation if elected

WASHINGTON (AP) — Donald Trump is pledging that as president, he would appoint a special prosecutor to probe the financial dealings of The Clinton Foundation.

Trump said Monday that the Department of Justice had "acted unethically" in probing Hillary Clinton's use of a private email server.

He also said the Justice Department and the FBI "can't be trusted" to investigate the foundation after declining to prosecute Clinton over the email scandal. He criticized Attorney General Loretta Lynch for meeting privately with former President Bill Clinton as the department's probe was underway.

"I've become increasingly shocked by the vast scope of Hillary Clinton's criminality," Trump told a crowd in Akron, Ohio.

He claimed that Clinton had overseen corrupt pay-for-play practices while heading the State Department.

Trump, campaigning Monday in Ohio, also criticized trade deals put in place by President Barack Obama and former President Bill Clinton.

"If you are not prepared to put American workers first, you should not be able to seek public office," Trump said at a rally in Akron.

He also bashed Clinton's immigration policy, saying it would lead to "open borders." Meanwhile, he doubled down on his own signature immigration plan.

"We're going to build the wall, folks. That wall will go up so fast your head will spin," Trump said. "You're going to say 'He meant it!' And you know what else I mean: Mexico is going to pay for it."

However, Trump is postponing a speech in which he was to lay out his immigration policy.

The Republican presidential nominee had been slated to unveil the proposal Thursday in Denver. A campaign official not authorized to publicly discuss Trump's plans said it was being postponed, likely until next week, but did not say why.

Trump promised in an interview Monday that he would deliver a "fair but firm" policy toward the 11 million immigrants living in the United States illegally.

That has raised questions about whether Trump is backtracking from previous pledges to push for mass deportations.

Trump has insisted he is not "flip-flopping" But he told immigration activists he may consider allowing those who have not committed crimes, beyond their immigration offenses, to obtain some sort of legal status.
