Tom Krause, a Silicon Valley executive with ties to DOGE, will become the fiscal assistant secretary of the Treasury Department, the people said. He replaces David A. Lebryk, who resigned after objecting to Krause’s demands to stop payments on foreign aid — a measure Lebryk resisted as illegal.

DOGE’s earlier actions at the Treasury have become a focus of congressional scrutiny and a federal court battle in recent days. Musk’s team initially tried to halt money going to the U.S. Agency for International Development from the Treasury’s payment system.

Democratic lawmakers have expressed concern that access to the system could allow DOGE, which disburses nearly 90% of all federal payments, to restrict disbursement of federal funds.
