text: WASHINGTON — President Trump added his former White House aide, Omarosa Manigault Newman, on Tuesday to the growing list of African-Americans he has publicly denigrated on Twitter, calling her “that dog” and a “crazed, crying lowlife” after her allegations against him of mental deterioration and racism. 
   
   Even for a president who consistently uses Twitter to assail his adversaries, the morning tweet about Ms. Manigault Newman was a remarkably crude use of the presidential bully pulpit to disparage a woman who once served at the highest levels in his White House. 
   
   In an interview on MSNBC, Ms. Manigault Newman responded that Mr. Trump treats women differently from men because he “believes they are beneath him” and that he talked in derogatory ways about minorities. 
   
   “He has absolutely no respect for women, for African-Americans,” she said. 
   
   In recent weeks, Mr. Trump has called Don Lemon, a CNN anchor, “the dumbest man on television.” He has questioned the intelligence of LeBron James, a star basketball player for the Los Angeles Lakers. And he has repeatedly said that Representative Maxine Waters, Democrat of California, has a “low I.Q.” ||||| White House: we cannot guarantee there's no tape of Trump using N-word 
   
   As the remarkable public spat between Donald Trump and former adviser Omarosa Manigault Newman continued on Tuesday, the White House was unable to guarantee that no recordings exist of the president using the “N-word”. 
   
   
   
   Omarosa says Trump is a racist who uses N-word – and claims there is tape to prove it Read more 
   
   At a White House briefing, press secretary Sarah Sanders was asked if she could say no such recordings would emerge. 
   
   “I can’t guarantee anything,” she said. 
   
   Sanders cited the president’s tweets on the matter and said: “I can tell you that the president addressed this question directly.” On Monday, Trump wrote: “I don’t have that word in my vocabulary and never have.” 
   
   On Tuesday morning, he added to earlier tweets when he wrote: “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 [John] Kelly for quickly firing that dog!” 
   
   Manigault Newman, a former contestant on the reality TV show The Apprentice, is promoting a memoir, Unhinged. She has released two secret recordings related to her firing from the White House late last year and another related to the claims that Trump used the “N-word” during his career in reality TV. 
   
   Sanders said she had never heard Trump use the racial epithet in question. 
   
   In an interview on MSNBC on Tuesday afternoon, Manigault Newman introduced another angle to the row when she confirmed earlier hints that she has been interviewed by special counsel Robert Mueller. The former FBI director is investigating Russian interference in the 2016 election and links between Trump aides and Moscow. 
   
   “I have” been interviewed, Manigault Newman said, though she said her “hands are tied” over any discussion of what she was asked. 
   
   Earlier in the day, the Trump campaign accused her of breaching a 2016 non-disclosure agreement. 
   
   In a statement to CNN, the campaign said it had “filed an arbitration against Omarosa Manigault Newman, with the American Arbitration Association in New York City, for breach of her 2016 confidentiality agreement with the Trump campaign”. It is the first legal action the campaign has launched since Manigault Newman revealed details in her tell-all book about her time as a Trump campaign adviser and senior White House aide. 
   
   On MSNBC, Manigault Newman said: “I don’t believe that I have violated [an NDA], but I’m going to leave that to the lawyers to sort that out. It’s interesting that he’s trying to silence me. So what is he trying to hide? What is he afraid of? If he hadn’t said anything that was derogatory or demeaning to African Americans and women, why would he go to this extent to try to shut me down?” 
   
   I think he should be afraid of being exposed as the misogynist, the bigot and the racist that he is Omarosa Manigault Newman 
   
   Asked if there were any more tapes the president should be “afraid of”, she said: “I think he should be afraid of being exposed as the misogynist, the bigot and the racist that he is.” 
   
   Of Trump calling her a “dog”, she said: “I think that it just shows you that if he would say that publicly, what else would he say about me privately? He has absolutely no respect for women, for African Americans – as evidenced by him instructing the chief of staff to lock me for two hours in the Situation Room to harass me, to threaten me. 
   
   “He’s unfit to be in this office and to serve as the president of the United States.” 
   
   At the White House briefing, Sanders said Manigault Newman was a “self-serving someone who blatantly cares about herself more than our country”. 
   
   Sanders also insisted that Trump’s decision to call Manigault Newman a dog and his other criticisms of prominent African Americans were not racially motivated. 
   
   “This has absolutely nothing to do with race,” she said, “and everything to do with the president calling out someone’s lack of integrity.” 
   
   She also complained about reporters only asking about “a few of the things that the president has said negative about people who are minorities” and said Trump was “an equal opportunity person who calls it like he sees it and always fights fire with fire”.

   Manigault Newman’s recent TV appearances, and her claim to have heard a tape of Trump using the N-word and other racial slurs during filming for The Apprentice, have clearly infuriated the president. 
   
   Did Omarosa break the law by secretly recording Trump and Kelly? Read more 
   
   On CBS, Manigault Newman revealed a third tape she said recorded a 2016 conference call among Trump aides discussing how to address potential fallout from any release of tapes that allegedly contain Trump using the N-word. The campaign aides had previously denied any such conversations took place. 
   
   In the recording, then campaign spokeswoman Katrina Pierson can be heard saying: “I am trying to find at least what context it was used in to help us maybe try to figure out a way to spin it.” Later in the conversation, she says: “He said it. He is embarrassed.” 
   
   On Monday night, Pierson said on Fox News the call “did not happen”. But in a statement on Tuesday, she said she had been seeking “to placate Omarosa to move the discussion along”. 
   
   Manigault Newman’s decision to record conversations has attracted controversy. When Kelly fired her in December in the White House Situation Room, she secretly taped the conversation: an apparent breach of security protocol. ||||| President Trump says former White House staffer Omarosa Manigault-Newman lied when she called him a racist who has said the N-word on tape. The president tweeted Monday night, "I don't have that word in my vocabulary and never have. She made it up." But a new recording, obtained by CBS News overnight, seems to back up Omarosa's story that several Trump advisers discussed an alleged tape during the 2016 campaign. 
   
   Trump campaign advisers denied on Monday that any conversations took place. CBS News has not been able to verify the authenticity of the recording - though it appears to confirm Omarosa's claims that Trump campaign officials were aware of a tape in which then-candidate Trump uses a racial slur, and they talked about how to handle it. 
   
   During her whirlwind book tour, former White House aide Omarosa claimed to have heard tape of President Trump using the N-word during his time on "The Apprentice." 
   
   In her new book, "Unhinged," Omarosa claims the Trump campaign was aware of the existence of the tape. She describes an October 2016 phone conversation with Lynne Patton, then-assistant to Eric Trump, spokesperson Katrina Pierson and campaign communications director Jason Miller in which they discuss how to deal with the potential fallout from its release. 
   
   Omarosa on Trump tapes: "If you see it in quotes it can be verified" 
   
   "I am trying to find at least what context it was used in to help us maybe try to figure out a way to spin it," Pierson is heard saying. 
   
   Patton then described a conversation she had with then-candidate Trump about making the slur. 
   
   Patton: "I said, 'Well, sir, can you think of anytime where this happened?' And he said, 'no.'" 
   
   Omarosa: "Well, that is not true." 
   
   Patton: "He goes, how do you think I should handle it and I told him exactly what you just said, Omarosa, which is well, it depends on what scenario you are talking about. And he said, well, why don't you just go ahead and put it to bed." 
   
   Pierson: "He said. No, he said it. He is embarrassed by it." 
   
   Appearing on Fox News Monday night before the release of the audio, Pierson denied the call ever took place saying, "No, Ed (Henry). That did not happen. Sounds like she is writing a script for a movie." 
   
   The White House and Trump campaign have not provided responses to this new development but Patton and Pierson issued a joint statement Tuesday morning saying, "No one ever denied the existence of conversations about a reported 'Apprentice' tape. Of course there were multiple discussions about it."
target: – President Trump insists that the "terrible and disgusting" n-word is simply not in his vocabulary—but White House press secretary Sarah Huckabee Sanders says she "can't guarantee" that recordings of him saying it will not emerge. "I can tell you that the president addressed this question directly," she told reporters Tuesday, per the Guardian. She denied that Trump's attacks on former Apprentice contestant and White House adviser Omarosa Manigault Newman, who says she has heard recordings of Trump using the slur, were motivated by racism, reports the New York Times. "The fact is the president's an equal opportunity person that calls things like he sees it," Sanders said. In an interview with MSNBC Tuesday, Manigault Newman confirmed that she'd been interviewed by Robert Mueller's investigators, though she declined to discuss details. Asked about Trump calling her a "dog," she said: "I think that it just shows you that if he would say that publicly, what else would he say about me privately?" Asked if there were more tapes Trump should be afraid of, she said the president should worry about being exposed as the "misogynist, the bigot, and the racist that he is." Manigault Newman, who's being sued by Trump's campaign organization for allegedly violating an NDA, provided a recording to CBS News in which Trump staffers appear to confirm the existence of an n-word tape and discuss the potential fallout.
