WikiLeaks is set to publish additional emails sent and received on Hillary Clinton’s private server during her time serving as secretary of state.

"We have upcoming leaks in relation to Hillary Clinton. …We have emails pending publication," the site’s founder, Julian Assange, told the U.K.’s ITV Sunday, according to The Guardian.

He did not indicate how many emails would be published to the site or when the release would occur.

Assange was speaking from the Ecuadorian embassy in London, where he has avoided extradition to Sweden over 2010 rape allegations.

WikiLeaks created a searchable database in March of Hillary Clinton emails where users can sift through an archive of 30,322 emails and attachments sent to and from her private server.

Assange has long been critical of the presumptive Democratic nominee, but told ITV that it was unlikely U.S. Attorney General Loretta Lynch would indict her.

"She’s not going to indict Hillary Clinton, that’s not possible. It’s not going to happen. But the FBI can push for concessions from a Clinton government," he said.

The FBI’s investigation into the unsecured private email system Clinton used while secretary of state between 2009 and 2013 has continued to dog her bid for the presidency.

Clinton has maintained that nothing sent or received on her server was marked classified at the time, but a 2012 email with classified markings released by the State Department contradicts that claim Fox News recently reported.

Government officials have found more than 2,000 emails on Clinton’s server that contain classified information. None of those were marked classified on her personal server, the State Department has said.
