"Every critic, every detractor, will have to bow down to President Trump," Manigault says in a trailer released Tuesday for a 2-hour Frontline PBS election special.
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.
