Ross apparently will host the event at his home in the Hamptons on Friday, according to Michelle Ye Hee Lee of The Washington Post.
Stills responded to the article by tweeting out a screenshot of the mission statement of Ross' non-profit, "Ross Initiative in Sports and Equality."
"We are a national nonprofit that educates and empowers the sports community to eliminate racial discrimination, champion social justice, and improve race relations." reads the statement.
A source close to Ross told Safid Deen of the South Florida Sun Sentinel that the owner doesn't support the president's views on race.
"They agree on some things and disagree on others, specifically on the rhetoric around race," the source said. "With regards to race, Stephen's record on fighting racism speaks for itself. It is possible to support someone on the basis of some things, and not agree with everything about them."
Ross provided his own statement on the matter:
According to The Post, the price of entry for Ross' fundraiser apparently ranges from $5,600 to $250,000.
Tickets priced at $100,000 will get attendees a photo opportunity with Trump, while the $250,000 package includes a seat at the private roundtable with the president.
