Washington (CNN) Omarosa Manigault Newman has released a new audio recording in which she and Lara Trump, the wife of President Donald Trump's son Eric, are discussing a job offer with Trump's re-election campaign that the former White House aide alleged was a hush agreement.

Manigault Newman writes in her book , "Unhinged: An Insider's Account of the Trump White House," that she turned down an offer from President Trump's daughter-in-law to sign a nondisclosure agreement in exchange for a job on the President's re-election campaign paying $15,000 per month. Manigault Newman said she was offered the deal after she was ousted from the White House last December.

Promoting her book this past week, Manigault Newman has released secret recordings she made of her conversations with the President and his aides, including a recording made in the White House Situation Room, raising national security questions.

In the newest audio recording released Thursday to MSNBC, Lara Trump, a senior adviser for Trump's 2020 re-election campaign, can be heard telling Manigault Newman "that there are some things you've got in the back pocket to pull out." Trump appears to reference a New York Times article published shortly after Manigault Newman left the White House that gave the impression that the former aide was open to discussing her time in the administration.

"Clearly, if you come on board the campaign, like, we can't have -- we got to -- everything, everybody positive, right?" Trump adds in the conversation with Manigault Newman.
