Crypto journalist Eleanor Terrett said she emailed the White House three times over the past week to inquire whether Patrick Witt still serves as executive director of the White House Crypto Council, and received no reply. Witt himself declined to comment. Sources familiar with the matter disclosed that Witt, a U.S. Department of Defense employee temporarily seconded to the White House Crypto Council, has reached or is nearing the end of his secondment, with his reappointment status unclear. Earlier this year, he delayed his service in the Georgia National Guard, and is expected to resume his military service soon. Terrett added that Harry Jung, deputy director of the White House Crypto Council, left his post at the end of July, and after David Sacks’ tenure as Crypto and AI “tsar” concluded, Witt is now the only remaining staff member of the council. The crypto policy community is now debating: after the CLARITY Act (officially the Crypto Market Structure Act) failed to advance in the Senate, whether the White House still prioritizes the crypto industry. The relevant personnel changes have not yet been officially confirmed by the White House.
