Senator Tammy Duckworth is calling on President Trump to veto the recently passed bill overturning Consumer Financial Protection Bureau (CFPB)’s rule limiting forced arbitration. She says the deck will be stacked in favor of big banks and financial institutions in cases of fraud and other misdeeds.

The mandatory arbitration rule, which was set to take full effect next March, would stop financial services companies from using forced arbitration clauses to block consumer class action suits.
