(AP)—A former computer security chief at the Department of Veterans Affairs is telling lawmakers that at least eight foreign-sponsored organizations have hacked into the department's computer networks in recent years or were actively trying to do so.

Jerry Davis served as the VA's chief information security officer until February 2013. He says in written testimony Tuesday to a House subcommittee that the VA became aware of the in March 2010 and that attacks continue "to this very day."

Davis says the hacking "successfully compromised VA networks and data," but he did not indicate how the information may have been used. The intrusions raise the potential for identity theft and could complicate efforts to share data with the Pentagon, long viewed as key to quicker processing of disability claims.
