“Chelsea Manning is somebody who accepted responsibility for the crimes she committed,” a senior White House official said, speaking on the condition of anonymity under ground rules set by the White House. “She expressed remorse for committing those crimes. She began serving the sentence that was handed down. The president’s concern was rooted in the fact that the sentence handed down is longer than sentences given to other individuals who committed comparable crimes.”
