In a long-form post on X, formerly Twitter, on Sunday, billionaire investor Bill Ackman criticized First Lady Jill Biden for prioritizing her own interests over the health and safety of the country. Ackman, who is the CEO of Pershing Square Capital Management, expressed his concerns about the First Lady’s influence on President Joe Biden‘s decision-making. He suggested that the stress she is causing the President is contributing to his “neurological deterioration.” Ackman said he no longer blamed Biden for not stepping down. He said, “It is becoming increasingly clear however that the fault lies with … Jill Biden.”
