Donald Trump is launching a new push to win over minority voters. His campaign revealed Sunday night that Trump will address the Impact Network --the only African-American-owned Christian TV network -- in Detroit on Saturday.

The visit comes as the Trump and Clinton campaigns continue to argue over race relations.

We’re still seeing the repercussions of what was truly a first: two presidential candidates accusing each other ofbigotry, reports CBS News correspondent Nancy Cordes. The Clinton campaign has followed up with a new ad fleshing out their accusations, while Trump courted controversy on the subject this weekend with, what else -- a tweet.

“What do you have to lose, you are living in poverty, you have no job. Oh, look at my African American over here,” Trump is heard saying in the new Clinton ad, which accuses the GOP nominee of racial insensitivity.

Trump gave them more fodder thisweekend after the cousin of an NBA star was killed in Chicago, tweeting​: “Dwayne Wade’s cousin was just shot and killed walking her baby in Chicago. Just what I have been saying. African-Americans will VOTE TRUMP!”

Clinton’s running mate chastised Trump.

“We just ought to be extending our sympathy to the family. That’s the only reaction that’s appropriate,” Tim Kaine said in Miami Lakes, Florida.

One day earlier, Kaine sought to tie Trump to the KKK.

“Ku Klux Klan values, David Duke values, Donald Trump values are not American values,” Kaine said.

Trump did eventually tweet his condolences to the Chicago family, and his supporter Gov. Chris Christie accused Clinton and Kaine of overheated rhetoric.

“This type of discourse in the campaign is just unwarranted. But it was started by Mrs. Clinton,” Christie said on ABC News.

Actually, Trump beat Clinton to the punch by about 12 hours, when he called Clinton a “bigot” in Mississippi.

“There’s been a steady stream of bigotry from him,” Clinton said in Reno, Nevada, the next day.

The two sides also tangling over the Clinton Foundation​ and the access its donors had to Clinton as secretary of state.
