Donald J. Trump, who has gone more than a year without holding a single event in a black community, plans to head to a predominantly black church in Detroit on Saturday and speak with the president of an African-American owned and operated national Christian television network.

The Trump campaign said the candidate will appear at Great Faith Ministries, where he will be interviewed by Bishop Wayne T. Jackson, president and chief executive of the Impact Network. The visit comes as several polls show Hillary Clinton winning an overwhelming majority of support from black voters across the country.

Faced with those stark poll numbers, Mr. Trump has recently begun asking black and Hispanic voters for their support but has made his appeal before mostly white crowds. But on Saturday, he will speak more specifically about his plans to help blacks, his campaign said.

”Mr. Trump will answer questions that are relevant to the African-American community,” Pastor Mark Burns, a surrogate for Mr. Trump, said in a statement. “He will then give an address to outline policies that will impact minorities and the disenfranchised in our country. Citizens around the country will see, as I’ve have seen, the heart and compassion Mr. Trump has for all Americans, which includes minority communities whose votes have been taken for granted for far too long.”
