Vice President Joe Biden says the Justice Department is looking at what the U.S. can do to stop more document releases from WikiLeaks.

Biden says he won't comment on that process, but has strong words about WikiLeaks founder Julian Assange.

Biden says if Assange conspired to get classified documents with a member of the U.S. military, then "that's fundamentally different" than if a reporter were given classified material by a source.

The vice president tells NBC's "Meet the Press" that he would argue it's closer to being "a high-tech terrorist" than what happened in the Pentagon Papers -- with the 1971 leak of a government study about U.S. involvement in Vietnam.
