Attorney General Alberto Gonzales is facing a possible perjury investigation over his sworn testimony on the Bush administration’s domestic spy program. On Wednesday, Senate Judiciary Chair Patrick Leahy said he may request the probe over Gonzales’ insistence that a March 2004 meeting with congressional leaders was not called to address the warrantless spying. Several lawmakers in attendance have denied Gonzales’ account. And newly released documents show then-Director of National Intelligence John Negroponte later described the meeting as a “briefing on the Terrorist Surveillance Program” — the same name administration officials use to describe the warrantless spying. Leahy says he will give Gonzales until next week to revise his testimony, or he will ask for a perjury inquiry.
