What Clapper did to Congress was no different from what Stone did to Congress: Clapper knowingly, intentionally, and deliberately lied to Congress when he falsely denied that U.S. national-security state officials were conducting secret mass surveillance on the American people.
What happened to Clapper? Nothing. No indictment. No criminal prosecution. No conviction. No sentencing.
