The Intercept, a digital magazine founded by journalists involved in the release of documents leaked by NSA contractor Edward Snowden, said some material was withheld at US intelligence agencies' request because it wasn't "clearly in the public interest." The Associated Press could not confirm the authenticity of the May 5 NSA document, which The Intercept said it obtained anonymously.

In its announcement of the arrest, the Justice Department said Winner, 25, of Augusta, Georgia, has been charged in US District Court with copying classified documents and mailing them to a reporter with an unnamed news organization. Prosecutors did not say which federal agency Winner worked for, but FBI agent Justin Garrick said in an affidavit filed with the court that she had previously served in the Air Force and held a top-secret security clearance.

Winner's attorney, Titus Thomas Nichols, declined to confirm whether she is accused of leaking the NSA report received by The Intercept. He also declined to name the federal agency for which Winner worked.

"My client has no (criminal) history, so it's not as if she has a pattern of having done anything like this before," Nichols said in a phone interview Monday. "She is a very good person. All this craziness has happened all of a sudden."In affidavits filed with the court, Garrick of the FBI said the government was notified of the leaked report by the news outlet that received it. He said the agency that housed the report determined only six employees had made physical copies. Winner was one of them. Garrick said investigators found Winner had exchanged email with the news outlet using her work computer.

Garrick's affidavit said he interviewed Winner at her home Saturday and she "admitted intentionally identifying and printing the classified intelligence reporting at issue" and mailing it to the news outlet.

Asked if Winner had confessed, Nichols said, "If there is a confession, the government has not shown it to me."Bynum reported from Savannah, Georgia.
