A US government contractor has been arrested on suspicion of leaking top-secret information to a news outlet.
Reality Leigh Winner, 25, allegedly removed classified material from a government facility in the US state of Georgia.
The charges were announced shortly after the Intercept published a National Security Agency briefing about alleged Russian political meddling.
The Trump administration has been railing against leaks to the media. The justice department said Miss Winner was arrested on 3 June.
She is a contractor with Pluribus International Corporation and had been employed at an NSA facility in Georgia since February.
According to reports, the accused faces a count of gathering, transmitting or losing defence information.
The Intercept’s leaked document alleges Moscow’s military intelligence services attempted cyber-attacks on at least one US voting software supplier days before last November’s US presidential election.
It also accuses them of sending spear-phishing emails to more than 100 local election officials.
However, there is no suggestion in the document that the hackers were successful, the NSA file in question was apparently marked for declassification not before May 2042.
