WASHINGTON — The FBI is looking into the security of the private email server that Hillary Rodham Clinton used when she was secretary of state.
The Washington Post also reported Tuesday that the FBI has asked Clinton lawyer David Kendall about the security of a thumb drive, containing copies of Clinton's emails, that Kendall possesses.
The Post report cited two anonymous government officials, but said Kendall confirmed that the government was investigating the security of the devices.

NBC News confirmed that the FBI is looking into the procedures used in the private Clinton server. The investigation involves a system, as opposed to a person.
Clinton's emails have been under scrutiny since it was revealed she used a private server in her Chappaqua, New York, home while she was the top U.S. diplomat. Government and congressional investigators have been trying to determine whether she sent or received classified information on unsecured email.
Last month, the inspector general of the U.S. intelligence community alerted the Justice Department about classified information included improperly on email that went through Clinton's home server. The referral to the Justice Department did not seek a criminal probe and did not specifically target Clinton.
The two officials cited by the Post also said that the FBI was not targeting her.
A spokesman for Clinton's presidential campaign tweeted Tuesday that that Post story "doesn't change anything ... IG sent ask to DOJ to confirm emails are secure."
"IG request was noncriminal & didnt accuse Clinton of wrongdoing," spokesman Brian Fallon tweeted. "FBI is 'not targeting her.'"
