Wikileaks founder Julian Assange is expected to find out whether he can halt his extradition to the US, where he faces trial for disclosing classified military information. Assange, an Australian national, founded Wikileaks in 2006 and has published over 100 million documents, many of them confidential. In 2019, the US sought his extradition, which the UK granted, though Assange continues to fight the decision.
