Reality Leigh Winner. Screenshot via Twitter Reality Winner, the 25-year-old Air Force veteran and federal contractor being charged with espionage on suspicion of leaking a top-secret NSA document to The Intercept, had apparently been vocal about opposing President Donald Trump and said she would "stand" with Iran in a hypothetical war with the US.

Winner publicly offered support to Iran after Iranian Foreign Minister Javad Zarif tweeted a video defending Iran's ballistic-missile program, which US officials under Trump and former President Barack Obama, as well as former UN Secretary-General Ban Ki Moon, had condemned as a violation of the spirit of the Iran deal.

Replying to Zarif's video on February 7, Winner tweeted: "There are many Americans protesting US govt aggression towards Iran. If our Tangerine in Chief declares war, we stand with you!"

She began her job as a federal contractor with top-secret clearance on or close to February 13, according to the Justice Department. The top-secret document she is accused of sending to The Intercept was created May 5.

In another tweet she described Trump as an "orange fascist." At least eight times, Winner retweeted a picture of a young girl with Trump-like hair and a long red tie with the hashtag "#largerhands."

The leaked NSA document, which The Intercept published Monday, details attempts from Russian military intelligence to hack the 2016 US presidential election.

"Releasing classified material without authorization threatens our nation's security and undermines public faith in government," Deputy Attorney General Rod J. Rosenstein said. "People who are trusted with classified information and pledge to protect it must be held accountable when they violate that obligation."

Under the Espionage Act, Winner faces up to 10 years in prison.
