Kellyanne Conway sounded off on the feud between Omarosa Manigault-Newman and President Trump, saying the former White House aide is "ungrateful" after all the opportunities Trump has given her.

Manigault-Newman, who is promoting her new tell-all book about her time in the Trump administration, has made a series of salacious allegations about the president, including that there is a tape of him using the N-word during her time on "The Apprentice."

She has also released secret recordings of members of Trump's inner circle, including what she claims is an October 2016 phone conversation in which campaign staffers Katrina Pierson, Jason Miller and Lynn Patton discuss the existence of the alleged N-word tape.

Trump took to Twitter to deny that he ever used the racial slur, calling Manigault-Newman "wacky and deranged," and praising White House Chief of Staff John Kelly for firing "that dog."

On "America's Newsroom," Conway said she's never heard Trump use any type of racial slur in her two-plus years working closely with him.

"[Manigault-Newman] never pulled me aside, never said to me, 'Hey, listen, I heard the president say this and I don't know what to do with it,'" Conway said. "So not only did I never hear it, but I think she's out there saying she had never heard it either."

She noted that shortly after Manigault-Newman was fired she was asked point blank if she thought Trump was a racist, and she answered that she did not.

"For somebody who had opportunity after opportunity by Mr. Trump ... for 15 years, it does seem ungrateful to go and record people in the Situation Room," Conway said.

She noted that even some Democrats and Trump critics have condemned Manigault-Newman for secretly recording White House staffers.

"People are very concerned about that."
