Why Elon Musk's team now has access to Treasury's payments system

Elon Musk has gained access to the federal payment system to help the Department of Government Efficiency monitor and limit government spending. This move faced resistance from Treasury officials, resulting in the retirement of senior official David Lebryk. DOGE officials have been asking for this access since then and then stepped up the pressure after Donald Trump's inauguration. Musk suggested the access intends to uncover fraudulent or illicit payments.
