Omarosa Manigault Newman and April Ryan traded barbs Sunday after the former reality TV star said the White House exploited American Urban Radio Networks' Washington bureau chief by leaking a colorful, unflattering story about her departure from the Trump administration.

"Don’t reference me or use my name. Keep my name out of your mouth," Ryan wrote on Twitter. "You have done enough. Your lies and crazy behavior are catching up to you. Can you say National Security breach? Lawyer up!"

[New: Trump: 'Wacky Omarosa' is 'hated' in the White House, will never work for me again]



Omarosa! I hear you mentioned me on Meet The Press. Don’t reference me or use my name. Keep my name out of your mouth. You have done enough. Your lies and crazy behavior are catching up to you. Can you say National Security breach? Lawyer up! — AprilDRyan (@AprilDRyan) August 12, 2018



Ryan's comments follow Manigault Newman's explosive interview Sunday on NBC's "Meet the Press," which aired a tape the former star of "The Apprentice" recorded in the Situation Room of White House chief of staff John Kelly talking to her about "leaving" her role in the Trump administration. The tape has raised concerns that Manigault Newman breached national security protocol by taking a recording device into what is supposed to be among the most secure parts of the presidential complex.

"He knew that John Kelly was going to take me into the Situation Room, and lock me in there, threaten me, and say that things were going to get ugly for me, and there would be damage to me reputation," Manigault Newman said Sunday, referring to President Trump. "And you know what, the next day there was damage to my reputation because they then put out a story using and exploiting an African-American reporter to say that I was running around the residence and trying to break into a Christmas party, which is ludicrous."

Ryan additionally slammed Manigault Newman as "evil" during a Sunday appearance on CNN's "Reliable Sources."

"She was complicit, but she was doing all this knowing that there was going to be a payoff in the end for her, and then once she got upset with him or he got upset with her or whatever happened, she decides to turn on him," Ryan said of Manigault Newman's initial support of Trump, despite now calling him "a racist, a bigot and a misogynist.” "She’s not a friend, she’s a liar, and I would say she’s evil," Ryan added.

Manigault Newman is promoting her book, "Unhinged," which is set to be released Aug. 14. Ryan also has a memoir coming out. Ryan's "Under Fire" will be widely available from Sept. 1.
