The Consumer Financial Protection Bureau (CFPB) is taking steps to place Google under formal federal supervision, subjecting the company to the same inspections as major banks.
The CFPB has been in talks with Google for months about the supervision order, which is yet to be finalized.
The exact concerns of the CFPB with Google are unclear, but it adds to Google's regulatory challenges in the U.S.
Google has recently lost a major antitrust trial and faces another trial over its advertising technology.
