Omarosa, usually referred to by only her first name, left the White House in December and Sunday's interview coincided with the release of her book, Unhinged: An Insider Account of the Trump White House, detailing her time there.
The former aide to President Trump did not specify exactly when the tape was purported to have been recorded, but said it was from the POTUS' time as the host of the corporate reality TV show The Apprentice.
She said: "It confirmed what I feared the most: that Donald Trump is a con and has been masquerading as someone who is actually open to engaging with diverse communities; but when he talks that way, the way he did on his tape, it confirmed that he is truly a racist".
Press Secretary Sanders said: "It's sad that a disgruntled former White House employee is trying to profit off these false attacks, and even worse that the media will now give her a platform, after not taking her seriously when she had only positive things to say about the President during her time in the administration".
While White House press secretary Sarah Huckabee Sanders flagged the "blatant disregard for national security", Singleton similarly sounded the alarm.
"I've never heard of a more serious breach of protocol", said Ned Price, who served as spokesman of the National Security Council in the Obama administration.
Ms Newman justified her action by saying that she had felt the need to protect herself.
In an MSNBC panel discussion about the recording release by Newman, the panel recalled the catestrophic employment of the former black outreach liasian for the White House.
Todd asked why she did not come to this conclusion sooner, noting that Trump had said many things over the years that people considered racist, including calling Mexicans "rapists" or saying that "both sides" were to blame for bloodshed during the white nationalist march in Charlottesville last year.
Manigault Newman had indeed been a staunch defender of the president for years, including pushing back, as the highest-profile African-American in the White House, on accusations that he was racist.
"Who in their right mind thinks it's appropriate to secretly record the White House chief of staff in the Situation Room?" tweeted Ronna McDaniel, chairwoman of the Republican National Committee. Reporters were called to the White House to watch her perform a re-enactment, and the photos of her performing a tremendous stretch, which she supposedly held for five minutes, were rejected as implausible.
Conway said "that is not what was offered" to Newman.
Conway went on to hit Manigault Newman for the recordings she allegedly made during her time in the White House.
The response from the White House was stinging.
"People now understand that she has a lot", a former White House official said.
Trump adviser Kellyanne Conway responded on ABC's This Week that confidentiality agreements in the White House exist for a reason.
