Texas’ current and former solicitors general are calling on the U.S. Supreme Court to take up a case that could cripple the Consumer Financial Protection Bureau.

Texas’ current solicitor general, Kyle Hawkins, is among a group of conservative state officials, including colleagues from Arkansas, Kansas and Georgia, who have signed an amicus brief Monday against the CFPB. Hawkins is also joined by Scott Keller, the former Texas solicitor general now at Baker Botts, who signed a similar brief on behalf of the Cato Institute.
