Sen. Elizabeth Warren, D-Mass., told CNBC that the Trump administration's overhaul of the Consumer Financial Protection Bureau has cost Americans $26.5 billion.

Warren released a report ahead of acting CFPB Director Russell Vought's hearing Thursday before the Senate Homeland Security and Governmental Affairs Committee.

The senator said the costs come from Vought rolling back rules capping credit card and overdraft fees.

Warren said in her report that $15 billion in consumer costs are due to the CFPB's decision to abandon a rule capping most credit card late fees at $8, CNBC reported. In 2024, the agency adopted a rule capping most credit card late fees at $8 and said it would save consumers $10 billion annually.

Warren said rolling back the CFPB's overdraft fee rule has cost consumers $7.5 billion. The previous rule would have capped most overdraft fees at $5.

The remaining $4 billion comes from the CFPB's decision to drop more than three dozen enforcement actions and settlements, Warren told CNBC.

Brian Johnson, a former CFPB deputy director and Capital One executive, faces Senate confirmation to be permanent leader of the bureau.

The Trump administration has made dismantling the CFPB a priority.

Last month, a federal appeals court blocked the Trump administration's plans to immediately reduce the workforce at the bureau by about two-thirds.

The Department of Justice previously sought to cut up to 90% of the bureau's employees but was blocked by the courts.

The CFPB was created by Congress after the 2008 ⁠financial crisis to police consumer financial products.

Trump and other high-ranking officials have called for the agency ⁠to ⁠be abolished, accusing it of being a politicized burden on free enterprise. Democrats and agency defenders say damaging the bureau amounts to a giveaway to industry at the expense of consumers.

Barred legally from enacting the most drastic actions, the administration has taken other steps to reduce the agency's operations. In May, the agency said it would reassign all staff to its Washington headquarters, a move likely to drive resignations.
