Her mother, Billie Winner-Davis told the Guardian her daughter graduated from H.M. King in Kingsville, Texas, excelled in academics, tennis, and athletics. She joined the military shortly afterward, Winner-Davis said.

Winner served in the U.S. Air Force from January 2013 until February of this year when she began working with Pluribus where she had top-secret clearance, the FBI affidavit said. Task & Purpose, citing an Air Force source, reported Winner served as an airman first class with the 94th Intelligence Squadron at Fort Meade, Maryland, until earlier this year. Winner-Davis told the Guardian her daughter, who is fluent in Farsi, Dari, and Pashto, had been a linguist for the air force.

“I never thought this would be something she would do,” Winner-Davis said. “I mean, she has expressed to me that she is not a fan of [President] Trump—but she’s not someone who would go and riot or picket.”Winner’s social-media activity suggests she was opposed to Trump’s election. On Twitter, where she was active under the name Sara Winners, she frequently criticized the Trump administration’s policies, praised Edward Snowden, and on election night tweeted: “Well. People suck.” Tweeting at the president on his immigration order banning the citizens of six Muslim or predominantly Muslim countries, she asked: “have you ever met an Iranian?”

Winner-Davis, her mother, said Winner called home Saturday to let her know she had been arrested, and “that she couldn’t really talk about it.”

“I am still in shock,” her mother said.

Winner was charged under the Espionage Act and, if convicted, faces up to 10 years in prison.
