Billionaire entrepreneur Mark Cuban removes a social media post after backlash over his appearance at a White House event tied to the TrumpRx platform. According to reporting, Cuban had posted content that drew criticism, and later deleted it, including remarks described as “cursing” or profanity. Multiple outlets say Cuban had faced public scrutiny after previously supporting Kamala Harris, but he argues his involvement is not political. Cuban says his focus is on lowering healthcare costs through the partnership and he thanks President Donald Trump for the initiative. The coverage also notes that Trump comments on Cuban’s presence with a joking remark calling his appearance a “big mistake.” The reports characterize Cuban’s deleted post as a response to critics who questioned the change in his political support and his participation in the White House event. Overall, the accounts describe Cuban’s appearance as linked to announcing or presenting the TrumpRx collaboration and his subsequent attempt to clarify the purpose of his involvement as health-cost reduction rather than endorsement of political figures.
