Billionaire hedge fund manager Bill Ackman is facing scrutiny from conservatives for his plan to support the 2024 presidential campaign of Rep. Dean Phillips (D-MN), who has prioritized sweeping diversity, equity, and inclusion initiatives.

Ackman, an investor who runs the New York City-based Pershing Square Capital Management, has come under the spotlight in recent months for his opposition to academia and corporations relying on DEI, which the hedge fund manager and Republicans have described as discriminatory due to the framework’s promotion of race-based curricula and hiring practices. Still, Ackman’s anti-DEI crusade didn’t stop the billionaire from announcing Saturday that he will pour $1 million into a super PAC boosting Phillips, the long shot President Joe Biden challenger who has campaigned on DEI and pushed legislation in Congress that would expand DEI across the United States, records show.
