The Senate Banking Committee is set to host the CEOs of Equifax and Wells Fargo next month as as both companies face the fallout of massive financial scandals that have dominated headlines and tarnished their names.

Wells Fargo CEO Timothy Sloan will testify before the Banking panel on Oct. 3, while Equifax CEO Richard Smith will appear on Oct. 4. Both executives are expected to face hostile questions from both parties after a series of missteps that have triggered federal investigations.

Sloan will likely face questions about the up to 3.5 million Wells Fargo accounts opened without customers’ consent, as well as the rampant sale of unwanted auto and life insurance policies through misleading tactics. His predecessor, John Stumpf, appeared before the Banking Committee in 2016 before retiring soon after.
