A federal judge on Tuesday refused to block the appointment of Mick Mulvaney as interim director of the Consumer Financial Protection Bureau, siding with the Trump administration in the legal fight over the leadership of the consumer watchdog. "Denying the president's authority to appoint Mr. Mulvaney raises significant constitutional questions," U.S. District Judge Timothy Kelly said. Kelly, a Trump appointee, rejected the argument in a lawsuit from Leandra English that she should be the interim leader of the consumer bureau that oversees banks, mortgage providers, credit card issuers and other financial services that affect millions of Americans.
