Donald Trump made a direct appeal to African-American voters in a law and order speech delivered in West Bend, Wisconsin Tuesday night. And he came down clearly on the side of law enforcement in the wake of riots in nearby Milwaukee. Our Grace Rauh has the story.

Donald Trump is jumping into the national debate over race and policing. At a rally outside Milwaukee Tuesday he delivered a tough-on-crime talk while the city nearby tried to recover from violent protests that began after police shot and killed an armed black man on Saturday.

"The violence, riots and destruction that have taken place in Milwaukee is an assault on the right of all citizens to live in security and to live in peace," Trump said.

Trump also used his speech to attack media executives, even though reports indicated the former chief of Fox News, Roger Ailes, is helping Trump prepare for the debates. Ailes was removed from Fox after being accused of sexual harassment.

A spokeswoman for the Trump campaign said Ailes has no formal or informal role in the campaign.

Hillary Clinton stumped in Philadelphia Tuesday, taking aim at Trump over his tax plan.

Trump has proposed ending the estate tax, but it only applies to estates worth more than $5.5 million.

"If Trump is as wealthy as he claims to be, it would save his family $4 billion," Clinton said. "Now I've got to tell you, I could find a much better use for those $4 billion. Early childhood, helping our veterans, helping our law enforcement."

Meanwhile, Clinton's email troubles seem to be lingering. The FBI gave Congress materials from its investigation into Clinton's private email server. The Clinton campaign says the information should be shared widely to prevent Republicans from selectively leaking the report to score political points.

Trump is expected to get his first classified briefing in the city on Wednesday. Critics have argued he is not qualified to be briefed on major security issues. Clinton's own credibility with classified information has been questioned, in connection with her use of a personal email server at the State Department.
