From FAIR's latest alert: "Last night, Senate Majority Leader Harry Reid (D-NV) filed a motion for cloture on the Bush-Kennedy bill. A motion for cloture is, in plain English, a motion to end debate on the bill. Due to timing requirements in the Senate rules, the vote on the cloture motion is likely to come THURSDAY EVENING!!! If debate is ended, the Senate is then able to move to a vote on final passage of the bill."

"FAIR is urging all members and activists to call their Senators NOW and urge them to oppose the motion for cloture!!!! If debate on the bill does not end, the Senate cannot vote on final passage of the Bush-Kennedy bill."

Michelle Malkin is also blogging the Senate proceedings today.

Update: "Spirits among conservative critics of the immigration bill have brightened today following several Senate votes that indicate at least 40 senators could block the bill during a cloture vote tomorrow. Well-placed sources tell me that activists are focusing their attention on the following list of senators:

Sam Brownback (R.-Kan.), Richard Burr (R.-N.C.), Saxby Chambliss (R.-Ga.), Larry Craig (R.-Idaho), Pete Domenici (R.-N.M.), Byron Dorgan (D.-N.D.), John Ensign (R.-Nev.), Mike Enzi (R.-Wyo.), Judd Gregg (R.-N.H.), Johnny Isakson (R.-Ga.), Jon Kyl (R.-Ariz.), Mary Landrieu (D.-La.), Trent Lott (R.-Miss.), Mitch McConnell (R.-Ky.), Claire McCaskill (D.-Mo.), Ben Nelson (D.-Neb.), Mark Pryor (D.-Ark.), Debbie Stabenow (D.-Mich.), John Sununu (R.-N.H.), Jon Tester (D.-Mont.), George Voinovich (R.-Ohio), Jim Webb (D.-Va.), and John Warner (R.-Va.)." says Robert Bluey.
