Sen. Patrick Leahy (D-VT), chairman of the Senate Judiciary Committee, suggested to U.S. Drug Czar Gil Kerlikowske in a letter released Thursday (PDF) that Congress may consider legalizing marijuana in the wake of Colorado and Washington voting in favor of regulating the drug similarly to alcohol.

But, Leahy wrote in the letter, he wants to know where the administration stands on the laws before the committee takes up the question.

“How does the Office of National Drug Control Policy intend to prioritize Federal resources, and what recommendations are you making to the Department of Justice and other federal agencies in light of the choice by citizens of Colorado and Washington to legalize personal use of small amounts of marijuana?” Leahy asked Kerlikowske.
