U.S. bank regulator chief unaware of any hacking cover-up: hearing

By Jason Lange and Dustin Volz WASHINGTON (Reuters) - The head of a U.S. banking regulator on Thursday said he was unaware of any efforts by his staff to cover up hacking of the agency's computers by a foreign government in 2010 and 2011, as outlined by a congressional report. Federal Deposit Insurance Corporation Chairman Martin Gruenberg told a hearing of the committee that published the report that he first learned of the security breach in 2011 when he was the FDIC's acting chairman.
