Sources tell the network it looks like either a CIA employee or contractor is to blame.

The documents stolen are in such a secure section that only a few hundred people have access to them.

President Trump, who once praised Julian Assange for leaking embarrassing documents of his rivals, is now reportedly "extremely concerned."

CIA director Mike Pompeo said, "It is time to call out WikiLeaks for what it really is, a non-state hostile intelligence service often abetted by state actors like Russia."

At the time of its initial publishing, WikiLeaks says the CIA documents it released are just the tip of the iceberg, claiming they've only released 1 percent of their trove on the organization.
