I asked him how he could have possibly voted for a law that so vastly expanded the government's spying powers. He told me that he was facing a tough election, but as soon as it was over he'd invite my organization, the American Civil Liberties Union, to testify before Congress about the Patriot Act's flaws and the threats it presented to privacy and civil liberties. "We'll work together to get this repealed," he promised. Unfortunately, that day never came, as the senator tragically died in a plane crash in October of 2002.

Almost 13 years later, the most egregious part of the Patriot Act, Section 215 -- which underlies the National Security Agency's call-records program -- is scheduled to expire on June 1. Some legislators want Congress to reauthorize it in its current form -- Senate Majority Leader Mitch McConnell has just introduced a bill that would do exactly that, extending it for another five years. Others want to make relatively minor changes. Congress shouldn't do either of these things. Unless Congress can coalesce around far-reaching reform, it should simply let the provision expire.
