Former House Speaker and failed presidential candidate Newt Gingrich is feeling pretty good about Donald Trump's minority outreach efforts, and predicted this week the GOP nominee would win more African-American votes than any Republican candidate in recent memory.

"Donald Trump is the first Republican I can remember who is explicitly saying to the African-American community, 'Things can be better, but not with Democrats in charge,'" Gingrich said in an interview on Fox News.

"If [Trump] continues to say it, and if he has the courage to go back to places like Chicago and say it, I think he's going get far more votes from the black community than any Republican in modern times,'" he said.

Trump is scheduled to attend a service at Great Faith International Ministries in Detroit, Mich., Saturday, where he will also sit down for an an interview with Bishop Wayne Jackson.
