Pollster Mark Mitchell, an adviser to Vice President JD Vance, says Susie Wiles, Trump's former chief of staff, warned him off criticizing Pfizer, which he called her old lobbying firm's "number one client."

Mitchell, whom Vice President JD Vance brought to the White House to brief Trump on his slipping support, the Washington Post reported, said on his podcast, The Honest Poll, that he was told to stop tweeting and to stop making "these people angry." The post he says set it off, from Nov. 10, 2025, noted that Pfizer had earned $74 billion in profits since its Covid vaccine was released. Journalist Paul Thacker posted the clip on Tuesday.
