In March, Clapper told the Senate Intelligence Committee that the NSA does not collect intelligence on Americans in bulk, at least "not wittingly." The intelligence director later apologized in writing and said that characterization was "clearly erroneous."
Paul said Snowden should not get off "scot-free" for leaking classified information. But the Kentucky Republican said in light of a district court's ruling that the NSA's phone records collection program is likely unconstitutional, he believes Snowden leaked information about a program that was breaking the law.
On the other hand, Paul said, Clapper's statements amounted to perjury.
"I do think what our government is doing is unconstitutional, and I really think that in order to restore confidence in our intelligence community, I think James Clapper should resign," he said.
