WikiLeaks founder Julian Assange offered to turn himself over to the United States and serve a prison sentence if President Barack Obama pardons Chelsea Manning, the whistleblower who leaked military and diplomatic documents while working as an intelligence analyst in the Iraqi capital of Baghdad in 2010. “If Obama grants Manning clemency, Assange will agree to U.S. prison in exchange—despite its clear unlawfulness,” WikiLeaks tweeted Thursday. Manning was jailed in a military prison in Fort Leavenworth in Kansas shortly after being sentenced to 35 years in August 2013. A year later a U.S. Army rejected a request for clemency.
