London, August 1 (RHC)-- WikiLeaks founder Julian Assange has said that his group has more information about U.S. Democratic presidential nominee Hillary Clinton's campaign which could be released soon. Assange spoke with reporters from the Ecuadorian embassy in London, where he has been hold up for four years.

WikiLeaks leaked thousands of e-mails last week which showed that the Democratic National Committee (DNC) and Chairwoman Debbie Wasserman Schultz had unduly backed Clinton during the party’s presidential primary.

The e-mail exchanges between seven top DNC members point to an insider effort to undermine the presidential campaign of Vermont Senator Bernie Sanders, including several stinging denunciations of him and his organization.

The Federal Bureau of Investigation, the FBI, and Justice Department are investigating a hacking of Hillary Clinton's presidential campaign as well as examining intrusions by hackers into other Democratic Party organizations, two law enforcement officials told CNN.

Assange said the release of the documents was timed to coincide with the start of the DNC. "That's when we knew there would be maximum interest by readers, but also, we have a responsibility to," Assange said. "If we published after, you can just imagine how outraged the Democratic voting population would have been. It had to had to have been before (the convention)."

Assange has also been under investigation in the US since his website WikiLeaks released secret U.S. military and diplomatic documents in 2010. He has been in the Ecuadorian embassy in London since Junw 2012 and has secured political asylum from the South American country after he lost a legal battle against extradition to Sweden, where he faces allegations of sexual assault.

It is believed that Assange’s extradition is a cover for sending him to the U.S, where he is wanted over the release of thousands of classified U.S. documents on the wars in Iraq and Afghanistan on his whistleblower website.
