Even while sitting behind bars in the London Tuesday, WikiLeaks founder Julian Assange warned he'll publish more top secret U.S. documents.
Assange turned himself in to Scotland Yard and now awaits a hearing on Dec. 14.
The 39-year-old Australian faces extradition to Sweden, where he faces rape and sexual molestation charges. He denies any wrongdoing in the case.
WikiLeaks' release of secret defense documents have been a diplomatic nightmare for the Obama administration. The White House has gone into global "damage control" mode over sensitive and embarrassing State Department cables.
"It puts people's lives in danger, threatens our national security, and undermines our efforts to work with other countries to solve shared problems," Secretary of State Hillary Clinton said.
But a WikiLeaks spokesman said the continued release of secret U.S. diplomatic cables would not be affected by Assange's arrest, nor by the news that Visa and Mastercard have cut off key funding sources for the operation.
In recent weeks, Assange has been in hiding, only appearing on video when his site dumped more documents.
"It's trying to make it as hard for us as possible to publish responsibly in the hope that it can get us not to publish anything at all," Assange said.
Assange has threatened to pull the trigger on a so-called doomsday plan if the site is shut down, or if there is a legal turn that WikiLeaks doesn't like.
That plan includes the release of a set of documents protected by a 256 character password.
