Donald Trump calls ex-Apprentice contestant a "dog" while repeatedly denying use of a racial slur

He also referred to the 44-year-old as a 'crying lowlife'.

Donald Trump has hit out at ex-Apprentice contestant and former political aide Omarose Manigault-Newman a "dog" in a scathing Twitter attack on Tuesday afternoon.

The attack on the former aide – who is often referred to mononymously as Omarosa – comes as the publication of her tell-all book looms ever closer.

Her book, Unhinged, is rumoured to feature a whole host of explosive allegations against the US President, including repeated use of a racial slur during her time on The Apprentice, which brought her fame.

Trump first met Manigault-Newman as a contestant on the show, before the president invited her to work at the White House.

It's understood that during her time at 1600 Pennsylvania Avenue, Omarosa – the former White House liaison to black voters – secretly recorded a number of conversations with Trump that allegedly include his saying a number of derogatory terms – including a racial slur.

Combatting this on Monday night, Trump hit back at the claims, saying: “There are NO TAPES of the Apprentice where I used such a terrible and disgusting word ... I don’t have that word in my vocabulary, and never have.”

Trump since took to Twitter on Tuesday to refer to Omarosa as a "dog", following weeks of heated back and forths.

“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,” the tweet read.

“Good work by General Kelly for quickly firing that dog!”

This isn't the first time the 45th President of the United States has referred to people as 'dogs'. In fact, there are several reported cases of Trump referring to another human as a canine.

Back in 2013, he called popular American artist Mac Miller an "ungrateful dog" following the release of his single 'Donald Trump'.

He also, bizarrely, referred to Twilight actress Kristen Stewart as "a dog" as allegations based around a cheating scandal shrouded her relationship with then-boyfriend Robert Pattinson.
