Sen. Elizabeth Warren, D-Mass., is calling for an internal investigation into the Consumer Financial Protection Bureau’s mission to change its name.

In a letter sent Monday to the Inspector General of the CFPB and published by The Hill, Warren wrote that her office is concerned that the name change “imposes unnecessary and significant costs on taxpayers and the business community, deprives the CFPB of funds it can use to protect consumers, and violates legal requirements.”

Since March, the agency began taking steps to officiate a rebrand under Acting Director Mick Mulvaney.

Mulvaney said the name change was an effort to realign the bureau with the statute that brought it into being, calling the move “a good, small way – but a very visible way – to send a message.”
