WASHINGTON (Reuters) - U.S. Federal Deposit Insurance Corporation Chairman Martin Gruenberg said Wednesday he was "deeply sorry" for a toxic workplace culture and his own mistreatment of employees.

Testifying before Congress, Gruenberg said he accepted the findings of an independent report that found widespread sexual harassment and employee mistreatment at the bank regulator. He also apologized for his own treatment of employees, after the report found he lost his temper multiple times with subordinates.
