Chronology of Senate immigration reform bill this year

A bill is about to be brought to the floor. From Migration Information Source on May 15, here it is:
January 2007
* Senators John McCain (R-AZ) and Edward Kennedy (D-MA) begin formulating a new comprehensive reform proposal.
* President Bush includes immigration reform in his State of the Union address, renewing his call for a temporary worker plan and a path to legalization for unauthorized immigrants.
March 2007
* Senate Majority Leader Harry Reid (D-NV) vows to “take up a bill before the August recess.”
* Attempts to introduce a bill in the Senate falter, and Senator Kennedy proposes using legislation produced last year by the Senate Judiciary Committee as a starting point for negotiations.
* Group of GOP senators begins meeting with DHS Secretary Michael Chertoff and Commerce Secretary Carlos M. Gutierrez to craft a Senate immigration reform bill. Senators John Cornyn (R-TX), Arlen Specter (R-PA), Jon Kyl (R-AZ), Mel Martinez (R-FL), and Lindsey Graham (R-SC) are among those looking to create a united position among Republican senators.
* On the House side, Representatives Luis Gutierrez (D-IL) and Jeff Flake (R-AZ) introduce the Security Through Regularized Immigration and a Vibrant Economy (STRIVE) Act.
* White House immigration reform principles leaked to press.

April 2007
* President Bush reaffirms his push for comprehensive reform that, in addition to improved border and interior enforcement, includes “resolving without amnesty and without animosity the status of the millions of illegal immigrants that are here right now.”
* Majority Leader Reid sets a deadline of May 14th to begin debate on an immigration reform bill in the Senate.
* On the House side, Rep. Zoe Lofgren (D-CA), chair of the Judiciary Subcommittee on Immigration, Citizenship, Refugees, and Border Security, embarks on a series of hearings on immigration reform components.
* A meeting between Republican and Democratic staff ends abruptly when negotiations turn sour, causing Republican staffers to walk out. Senators decide they will negotiate in person to overcome the stalemate.
May 2007
* Majority Leader Reid vows to bring the immigration bill that passed the Senate in 2006 to the floor and bypass the committee process, unless a reasonable alternative to the bill is proposed by May 14th.
* Senators scramble to reach consensus before the May 14th deadline.
* Key Republican senators, including Lindsey Graham (SC), Mel Martinez (FL), John McCain (AZ), and Arlen Specter (PA) threaten to vote against last year’s Senate-passed bill if brought to the Senate floor. Senators urge Reid to allow time to finish negotiations and introduce a new bill. Reid finally relents and postpones the vote until the 16th.
* In the House, subcommittee hearings on immigration continue.
* President Bush uses his May 12th weekly radio address to continue his call for comprehensive immigration reform.
