Which Senate bill on immigration has been called to the floor for debate today? The one out of the Judiciary Committee.. the House version or Frist's version?
None of the above. Senators were talking in Morning Business.
But to your bigger question, the immigration bill that will be debated will be the one produced by the Senate Judiciary Committee. Frist's Bill will be brought up, and the Committee "markup" will be a lock-stock-and-barrel substitute amendment. That may happen this evening, if not, it will happen tomorrow morning.
