Chelsea Manning has filed her candidacy to run for U.S. Senate in Maryland, challenging Sen. Benjamin L. Cardin in this year's election. She'll be running as a democrat.

She declared her intentions a week ago with the Federal Election Commission. She has not openly talked about here Senate campaign much yet, but she has talked about some political issues on Twitter, saying among other things that "police kill hundreds of people every year with absolute impunity," stirring controversy with that statement, of course, especially as she did that on National Law Enforcement Appreciation Day.

When talking about transgender rights as well as bullying, she wrote in an article that "We need to stop asking them to give us our rights. We need to actually take the reins of government and fix our institutions."

Manning is a transgender woman who was convicted of sharing military documents (some of which relating to Guantanamo Bay) with Wikileaks and sentenced to 35 years in prison, sentence that was commuted by Obama in his final days as a president.
