Republican Senator Arlen Specter (PA), took AG Alberto Gonzales to task yesterday for his repeated prevarication on the subject of just what went down in the hospital room of his predecessor several years back. Here, from Time Magazine, we have an interesting side note (emphasis mine):

Specter later circled back to Gonzales on the matter, warning him: “My suggestion to you is you review your testimony to find out if your credibility has been breached to the point of being actionable,” Specter said. The maximum penalty for being caught lying to Congress is five years in prison and a fine of $250,000 per count. Specter wryly noted to reporters during a break that there is a jail in the Capitol complex.
