President Joe Biden said Wednesday that he is considering a request from Australia to drop the decade-long U.S. push to prosecute Wikileaks founder Julian Assange for publishing a trove of American classified documents.

For years, Australia has called on the US to drop its prosecution against Assange, an Australian citizen who has fought U.S. extradition efforts from prison in the U.K. Asked about the request on Wednesday, as he hosted Japanese PM Fumio Kishida for an official visit, Biden said, “We’re considering it.” Assange has been indicted on 17 espionage charges and one charge of computer misuse over his website’s publication of a trove of classified US documents almost 15 years ago.
