Chelsea Manning, a transgender woman who was convicted in 2013 of leaking thousands of classified documents to WikiLeaks, has filed paperwork to run for the U.S. Senate in Maryland.
Manning, whose 35-year prison sentence was commuted by President Barack Obama during his final days in office, has remained an outspoken activist on intelligence and transgender-rights issues. Her case remains deeply controversial, particularly among conservatives, who criticized Obama’s decision.
Manning would be a primary challenger to Sen. Ben Cardin (D-Md.), who is currently the ranking member on the Senate Foreign Relations Committee. Cardin has served two terms in the Senate and two decades in the House. He won reelection in 2012 by just over 30 points.
President Donald Trump has called Manning an "ungrateful traitor."
