Manigault-Newman, a star of Trump's former reality TV show "The Apprentice" and a White House adviser until her firing late past year, now is on a publicity tour for her new book, a tell-all account of the Trump administration. She said she has known Trump for 15 years and worked for his administration for 11 months.
The comments were made after DeVos visited Howard University in May 2017 and was booed by the student body.
On the recording, which has not been independently verified by ABC News, the younger Trump appears to suggest campaign concerns about Manigault Newman disparaging her former employers.
In her book Omarosa she said: "It's my opinion that Melania was forced to go to the border that day in June, essentially, to mop up her husband's mess". MSNBC also played the GOP video for Manigault Newman during its interview with her.
The audio corroborates Manigault Newman's claim that the Trump campaign sought to buy her silence.
Newman did not offer any concrete evidence in her book to back up her claims.
"Can you stand at the podium and guarantee the American people will never hear Donald Trump utter the N-word on a recording in any context?" the reporter asked. "Genuinely, because I don't think I believe numerous people that come out of the White House, because you don't know what to believe when you've been gaslighted to a point that you don't know what the truth is".
Manigault-Newman is on the opposite end of the political and ideological spectrum from Clyburn, who said most Republicans were "enablers" of the president.
"This just the beginning of the type corruption in Trump world", Newman said to Melvin, "and I am here to blow the whistle".
"When you give a crazed, crying lowlife a break, and give her a job at the White House, I guess it just didn't work out", tweeted Trump last August 14.
The reported split over how to handle Omarosa is just the latest among the first lady and Trump, who considers himself to be a masterful media strategist. All of this begs the question, if you knew he was a racist and said "inappropriate things" to you, why did you continue to work for him?
"There are things that I am going to save to share when the time is right", Manigault Newman said Wednesday on MSNBC.
A subsequent clip on the view sees her brag 'You all know him as the president.
