In court, AP observers wrote that Assange appeared “upbeat and relaxed”, at times cracking jokes with the judge.
While signing his plea agreement, he made a joke about the nine-hour time difference between the UK and Saipan.
At another point, when the judge asked him whether he was satisfied with the plea conditions, Assange responded: “It might depend on the outcome,” sparking some laughter in the courtroom.
“So far, so good,” the judge responded.
