Manning, 30, who is formerly known as Bradley Manning, was convicted in 2013 of the largest leak of classified documents in U.S. history and was sentenced to 35 years in prison. Last year, then President Obama commuted Manning’s sentence to time served and she was released from a military prison in Kansas.

Manning moved to Maryland after her release and friends and family raised more than $175,000 to support her through an online campaign. Since then, she has written for The Guardian and Medium on issues of transparency, free speech and civil liberties, according to her web site.

Manning’s statement of candidacy was filed with the Federal Elections Commission on Thursday. She is running as a Democrat and refers to Maryland as her “home state” on her web site.
