Customers of SoulCycle and Equinox have launched a boycott, following reports that Miami Dolphins owner Stephen Ross — a major shareholder in the high-end fitness chains — is planning a fundraiser for Donald Trump’s campaign. President Trump is expected to attend the event in the Hamptons this evening, which promises donors a photo with the president for $100,000 or a private roundtable discussion with Trump for a quarter-million dollars. Ahead of the event, Dolphins receiver Kenny Stills noted that Ross is founder of the nonprofit group RISE, which seeks to “eliminate racial discrimination, champion social justice and improve race relations.” Stills tweeted in reply, “You can’t have a non profit with this mission statement then open your doors to Trump.”
