Joe Biden’s brother told execs at a health care company that the former veep’s cancer initiative would help promote their business — during a pitch on behalf of potential investors, Politico reported Thursday, citing a source.

Biden’s brother James made the promise to brass at Integrate Oral Care of Florida during a phone call in November 2018, according to Michael Frey, CEO of Diverse Medical Management, a health care firm that was suing James.

James’ business partners were considering a possible investment in Integrate, according to Frey, who had a business relationship with James and had introduced the group to Integrate.

James told the Integrate executives that he would get the Biden Cancer Initiative to promote an oral rinse manufactured by the firm and used by many cancer patients, Frey told the website.

He said James mentioned his veep brother Joe on the call.

“He said his brother would be very excited about this product,” Frey said.

A spokesman for James denied Frey’s version.

“These charges stem from a frivolous lawsuit and are pure fantasy. We are not surprised that such baseless accusations have emerged during the Democratic primaries,” David Fuscus, a spokesman for James and Platinum Global Partners, told Politico, referring to a suit involving a business dispute James had with former associates.

“Jim Biden has been clear and consistent that he does not, and has never, discussed his business ventures with his brother.”

The Biden Cancer Initiative was a foundation launched by Joe and his wife, Dr. Jill Biden, in 2017 to support cancer research.
