This is becoming quite the feud!

Donald Trump is fighting back, after Omarosa just went on a press tour for her new book Unhinged and accused him of being racist and using the N-word, among other things, and the POTUS isn't playing nice.

"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. Good work by General Kelly for quickly firing that dog!" he tweeted.

".@MarkBurnettTV called to say that there are NO TAPES of the Apprentice where I used such a terrible and disgusting word as attributed by Wacky and Deranged Omarosa. I don’t have that word in my vocabulary, and never have. She made it up. Look at her MANY recent quotes saying such wonderful and powerful things about me - a true Champion of Civil Rights - until she got fired. Omarosa had Zero credibility with the Media (they didn’t want interviews) when she worked in the White House. Now that she says bad about me, they will talk to her. Fake News!" he added.

The former White House staffer claims that Trump was recorded on tape using the racial slur, and she's telling every media outlet that will listen.

“He was talking about some African Americans in the production during the course of The Apprentice, which is unacceptable. Here’s the thing. Why don’t we ask Donald Trump a simple question — ‘Donald J. Trump, have you ever used the N-word?’ — and allow him to respond? Because the people who have this tape intend to release this tape," she said during an explosive Today interview with Savannah Guthrie.

White House Press Secretary Sarah Huckabee Sanders moved quickly to dismiss the claims, too.

"[Omarosa's book] is riddled with lies and false accusations. It’s sad that a disgruntled former White House employee is trying to profit off these false attacks, and even worse that the media would 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," she told reporters.

We asked Trump supporter Roseanne her opinion on the controversy when we caught up with her at LAX yesterday. Watch to see what she had to say!
