Last week, two blizzards knocked Congress (and the rest of the federal government in Washington, DC) out of commission.
The snow kept the House out the entire week preventing them from taking any votes.
The Senate was only slightly more productive—confirming Joseph Greenaway to be U.S. Circuit Judge for the Third Circuit. Also, the controversial nomination Craig Becker to be a member of the National Labor Relations Board was blocked. On February 22, the Senate will begin debate over another stimulus/special interest spending bill.
