In one of his last moves in office, President Obama has commuted the 35-year prison sentence of Chelsea Manning, the Army private who leaked a massive trove of military secrets to WikiLeaks.The former intelligence analyst's prison sentence has been shortened to expire on May 17, 2017, according to a statement from the White House.This commutation was issued along with 208 others, including one for Oscar Lopez-Rivera, who was part of a militant group that fought for Puerto Rican independence. Obama also pardoned 64 individuals, including retired Gen.

She has admitted to "releasing more than 700,000 documents, including battlefield reports and U.S. embassy cables."Her lawyers at the ACLU expressed relief after the decision, saying that Manning has already served more time behind bars than any other whistleblower in U.S. history, and under difficult conditions."Since she was first taken into custody, Chelsea has been subjected to long stretches of solitary confinement — including for attempting suicide — and has been denied access to medically necessary health care," said lawyer Chase Strangio in a statement.
