The hearings before the Senate Banking Committee have high stakes for both companies, as lawmakers are expected to ask the CEOs whether they should be fired.
Sen. Elizabeth Warren, D-Mass., called for bipartisan action against Equifax during a Senate floor speech on Tuesday, criticizing the credit bureau for waiting several weeks after a massive data breach to reveal it to the public.
Senate Democrats' legislative bid to reform the credit reporting industry is tempered and balanced, according to analysts, which could help it gain traction in the GOP-controlled Congress.
The bill would create a federal obligation for credit reporting agencies to offer free credit freezes and prevent them from selling consumer information while a freeze is in place.
In order to compensate victims of the breach, Equifax is offering free credit monitoring services that include a mandatory arbitration clause, a measure Democrats were highlighting to lobby support for the CFPB's rule banning such clauses.
Senate Banking Committee Chairman Sen. Mike Crapo, R-Idaho, said he is considering holding another hearing on Wells Fargo following the bank's recent missteps.
Payday lenders and arbitration supporters are claiming the CFPB has met more often with consumer groups than industry, laying the groundwork for likely lawsuits on key rules.
