Reps. Judy Chu (D-Calif.) and Gwen Moore (D-Wisc.) unexpectedly stormed into House Speaker Mike Johnson’s office on Wednesday, challenging him over Elon Musk’s team’s access to a Treasury Department payment system.

Their intrusion occurred soon after Treasury Secretary Scott Bessent arrived at the speaker’s office to discuss how to carry out President Donald Trump’s tax agenda, amid a growing Democratic backlash against Musk’s takeover of the federal government.

Moore, however, claimed that when she and Chu confronted Johnson, Bessent was not present, Politico reported.

“Gwen Moore forced her way in there, and then I got to go in right behind her,” Chu told reporters. “And she was already confronting Speaker Johnson about Treasury Secretary Bessent and the stealing of Americans’ private information, tax information that should never be stolen and given to this billionaire Elon Musk.”

Last weekend, Bessent provided access to the payments system to members of Musk’s alleged Department of Government Efficiency while in Johnson’s office meeting with House Ways and Means Chair Jason Smith (R-Mo.). Trillions of dollars in tax refunds, Social Security payments, and numerous other government operations are managed by the system.

Musk’s team currently has “read-only” access to the system, the Treasury Department informed lawmakers on Tuesday, and their review “is not resulting” in any delays or suspensions of federal agency-approved disbursements.
