The Senate devotes its day to discussions on the nation's budget and the new health care law.

The Senate Tea Party Caucus convenes for the first time Thursday morning. Sens. Jim DeMint, R-S.C., Mike Lee, R-Utah, and Rand Paul, R-Ky., meet with representatives from several grass roots Tea Party groups.
