A British judge sent Julian Assange to jail Tuesday, denying bail to the WikiLeaks founder after he vowed to fight efforts to be extradited to Sweden in a sex-crimes investigation.

Despite Assange’s legal troubles, a WikiLeaks spokesman insisted the flow of secret U.S. diplomatic cables would not be affected. He also downplayed efforts to constrict the group’s finances after both Visa and MasterCard cut off key funding methods Tuesday.
