"Lying to Congress is a federal offense, and Clapper ought to be fired and prosecuted for it," Sensenbrenner said.
During a Senate Intelligence Committee hearing in March, Clapper told lawmakers that the National Security Agency does not collect information on Americans in bulk, at least "not wittingly." After secret NSA documents were leaked by Edward Snowden, Clapper apologized for the comment and called it the "least untruthful" answer available to him. That did not satisfy Sensenbrenner.
"The only way laws are effective is if they're enforced," Sensenbrenner said. "If it's a criminal offense — and I believe Mr. Clapper has committed a criminal offense — then the Justice Department ought to do its job."
