The younger brother of Joe Biden allegedly attempted to leverage his standing with potential business partners by fraudulently promising them the former Vice President would implement their health care models into his 2020 campaign, a new court filing in Tennessee reveals.

Over the past few years, several accusations of Joe Biden's relatives attempting to profit from his public standing have arisen, but the new filing provided the first explicit claims that James Biden offered up his brother's influence to benefit his own private business pursuits.

Filed by executives of two firms, Azzam Medical Services and Diverse Medical Management, who both provide rural healthcare solutions, the allegations came in sworn testimonies filed in federal court Friday against James Biden.

None of the allegations imply any wrongdoing on Joe Biden's part, or suggest that he had any knowledge of his brother's purported assurances.

James Biden allegedly promised prospective business partners the former Vice President would implement their health care models into his 2020 campaign. None of the allegations imply any wrongdoing on Joe Biden's part, suggesting neither he had no knowledge of his brother's purported assurances.

Azzam Medical Services and Diverse Medical Management originally sued James Biden and his business associates in June, claiming the cohort duplicitously offered to pair with both of the firms in a fraudulent scheme mapped out to bankrupt them and steal their business models.

As first reported by Politico, Friday's filing laid bare new details of three executives' interactions with James.

According to one such recollection, Diverse Medical Management's CEO Michael Frey says James Biden pledged to enlist the help of his older brother to help the firm secure contracts for court-ordered outpatient care.

Frey said he first met with James Biden in January 2018 at a hospital in Pineville, Kentucky, where Frey made a presentation detailing how his firm operates.

'During my presentation regarding intensive outpatient treatment, James Biden interrupted me to say, "My brother needs to have you in every court system in America,"' Frey claims in the filing, adding, 'I left the meeting very excited and optimistic about the future of DMM [Diverse Medical Management].'

Diverse Medical Management's CEO Michael Frey (above) says James Biden pledged to enlist the help of his older brother to help the firm secure contracts for court-ordered outpatient care, In his testimony, Mohammad Azzam, Frey's business partner, said in the months leading up to Joe Biden's presidential bid, during a phone call, James promised 'that the DMM psychiatric care model would be used by Joe Biden as part of his campaign.' In a separate call, Azzam cites to have taken place last fall, 'James Biden mentioned that his brother's connections to labor unions and the Department of Veterans Affairs would help DMM expand its model nationwide.'

After several months of negotiations, Frey and Azzam eventually struck a deal with Biden and his partners in August 2018.

The deal called for $10 million in investments into the pair's business. For months, the lawsuit claims, Biden – and his associate Michael Lewitt – promised investment money was just around the corner, and encouraged them to start buying up hospitals and medical firms in advance of the payment.

However, no such investment ever arrived.

The allegations made by Cohen, Azzam, and Frey echo those made previously by executives at Paradigm Global Advisors, a now ceased hedge fund firm run by James Biden and Joe Biden's son, Hunter, that were given to Politico previously. In a response to the original complaint, James Biden and his associates have denied engaging in any fraudulent scheme

Mitchell Cohen, Diverse Medical Management's former general counsel, also made a similar declaration to Frey and Azzam.

Cohen alleges that during a dinner in Philadelphia in September, James Biden reportedly said his brother had connections at the Department Veterans Affairs that could help their firm land VA contracts.

He also 'stated that he could facilitate contracts between DMM and first responders based on the relationships that his brother had with certain labor unions,' Cohen claims.

'[James] Biden and his wife, Sara, have a long-held and passionate commitment to finding solutions for the improved treatment of both substance abuse and post-traumatic stress disorder and the linkage between them, particularly in rural areas where so many local hospitals are failing,' a statement read.
