It's sole director would be removable at will by the president, and its budget would be controlled by Congress through the traditional appropriations process.The CFPB currently has expansive power to crackdown on what it considers "unlawful and abusive practices," can write regulations on the financial industry and is funded through the Federal Reserve.Panel Republicans lambasted the CFPB as an abusive threat to the economy and to constitutional separation of powers, while Democrats touted the more than $11 billion the agency returned to consumers through enforcement actions.Democrats offered several amendments to strip those provisions from the bill, which also fell along party line votes.Throughout the hearing, Democrats criticized Republicans for starting with a massive, 500-page bill combining bipartisan measures with long-sought GOP targets.Several asked Hensarling to abandon the CHOICE Act in favor over a bill focusing on community and mid-size banks.
