The Federal Trade Commission faces a “mortal threat” from the new Consumer Financial Protection Bureau, former Federal Trade Commission chairman Timothy Muris said during a panel discussion Thursday.

“I fear for the FTC,” said Muris, chairman of the agency from 2001 to 2004 and now of counsel to Kirkland & Ellis and a professor at George Mason University School of Law, because the CFPB could one day make it obsolete. He suggested that FTC leaders selectively criticize the rival agency publicly and privately.
