Transgender activist and leaker of national security documents Chelsea Manning showed up to the White House on Thursday morning to protest President Trump's Wednesday announcement of his decision to ban transgender people from serving in the U.S military.

Manning posted a photo to Instagram, and called the White House the "new ground zero of the war on trans people."

President Trump's announcement that transgender people would be barred "in any capacity" from serving in the military drew immediate complaints from Republicans and Democrats, and raised immediate questions about how it would be implemented. The Defense Department indicated it was not prepared to implement the decision, and the White House said it still had to coordinate with the department on questions such as how to handle the thousands of transgender people currently serving.

Manning was an intelligence analyst for the U.S. Army and sentenced to 35 years in prison after being convicted of leaking a trove of documents to WikiLeaks. Manning was pardoned by President Obama in January just before he left office.

The former Intel analyst also used Twitter to argue against Trump's plan.
