Show insiders from America's The Apprentice have claimed Donald Trump demeaned women with sexist language and rated contestants by the size of their breasts.
Former crew members, editors and contestants were interviewed by the Associated Press separately, but many gave similar accounts of his inappropriate behaviour.
Camera assistant Rebecca Arndt also claimed he would stop the production to make comments about her in front of the crew.
Contestant Gene Folkes also claimed the current Presidential candidate called for women contestants to wear dresses, which were shorter and showed more cleavage in one series.
She also alleged that he asked one contestant for her bra size and asked if they were real or natural.
Randal Pinkett, who won the show in 2005, criticised Trump during his run for President and revealed he used to discuss which female contestants he'd like to sleep with.
A crew member who asked not to be identified claimed he would also ask male contestants which of the female contestants they would sleep with.
But Hope Hicks, Trump's campaign spokeswoman said the claims are, "outlandish, unsubstantiated, and totally false claims fabricated by publicity-hungry, opportunistic, disgruntled former employees. [They] have no merit whatsoever."
Other cast and crew interviewed also said they have not heard anything which made them uncomfortable and had only had positive and professional experiences with the TV host.
