 WikiLeaks founder Julian Assange has returned to his homeland, Australia, aboard a charter jet, hours after pleading guilty to obtaining and publishing U.S. military secrets. The plea deal required Assange to admit guilt to a single felony count, but also permitted him to return to Australia without any time in an American prison. The judge sentenced him to the five years he'd already spent behind bars in the U.K., fighting extradition to the U.S. on an Espionage Act indictment. Julie Walker reports.
