Leaked audio of Donald Trump's callous remarks about women and sexual assault before a 2005 interview with NBC's Billy Bush dealt a major blow last week to the GOP nominee's presidential campaign. But it might just be the tip of the iceberg.

Reports surfaced Sunday that unaired footage from Trump's time on NBC's "The Apprentice" contained more inflammatory language from the businessman-turned politician, potentially including Trump using racial slurs. Though the tapes have not been released, former "Apprentice" producers have opened up about Trump's behind-the-scenes demeanor and media outlets are scrambling to get their hands on the audio. 

Here's everything we know about "The Apprentice" tapes:

Former Producers: 

Bill Pruitt, a reality TV producer who worked on a few early seasons of "The Apprentice" tweeted Monday that the language contained in the alleged unaired footage was even more offensive than the Billy Bush tapes, in which Trump said that "when you are a star you can do anything you want [to women] ... you can grab them by the p----."

Screenwriter and producer Chris Nee tweeted Sunday that she signed a contract stipulating that she would have to pay $5 million if she released footage from the show without "Apprentice" executive producer Mark Burnett's permission.  She said the footage would show Trump using a racial slur to describe black people. 

Mark Burnett

Politico reported Sunday that Burnett favored Trump in the upcoming election and was refusing the release the tapes of the unaired footage and audio and had threatened producers under his employ not to leak any tapes. Burnett responded with a statement Monday arguing that he has no legal authority to release any footage and had only urged producers to comply with the law.

"Despite reports to the contrary, Mark Burnett does not have the ability nor the right to release footage or other material from 'The Apprentice.' Various contractual and legal requirements also restrict MGM's ability to release such material," read a joint statement from Burnett and studio MGM, which owns Burnett's production company, released to CNN. "The recent claims that Mark Burnett has threatened anyone with litigation if they were to leak such material are completely and unequivocally false."

Transcripts

While all the unaired footage remains locked away somewhere, The Huffington Post was able to obtain the written transcript of one episode's worth of unaired footage from 2010. The transcripts reveal Trump making disparaging mark's about female contestant Emily West's looks. 

"I assume you’re gonna leave this off, don’t put this shit on the show, you know. But her skin, her skin sucks, okay?" Trump said of the musician during one of the show's boardroom scenes, according to the transcript. "I mean her skin, she needs some serious f------ dermatology."

Willing To Pay

David Brock, a Hillary Clinton supporter who runs Media Matters and a network of other Democratic groups that aid Clinton's campaign has said he would pay a hefty sum to see the unaired footage released. Brock said he would cover the legal fees of anyone willing to leak the damning audio, according to Politico

A GoFundMe page called "Trump Sunlight Campaign" has collected more than $24,000 in just over a day with a goal of raising money to support anyone willing to leak footage. The camaign's target amount is $5.1 million. 

"Someone out there is likely in possession of a piece of evidence that could be used to substantiate what many folks have always believed; that the current nominee for President of the United States is not a moral leader for us all to look to over the next four years," the page reads. "This country needs that person to come forward and ensure that we all know the truth that is out there."
