Manigault, who announced in July she was the Trump campaign's director of African-American outreach, appears regularly on television on behalf of the GOP nominee.

"Donald Trump is running for president because he believes that he can help turn the nation around," she says in the trailer for the PBS special, which premiers on Sept. 27.
