Federal Housing Finance Agency Director Bill Pulte has, improbably, become the Trump administration’s biggest hatchet man, railing against Federal Reserve Chairman Jerome Powell and others while serving as the government’s top housing regulator.

Pulte, a businessman and philanthropist, was nominated by President Donald Trump after the 2024 election to lead the FHFA, which oversees the government-sponsored enterprises Fannie Mae and Freddie Mac. The role typically gets little media attention, but Pulte, who has cultivated a massive following on X over the years, has drawn notice for his willingness to attack Trump’s rivals.
