Coverage of the new Heritage Foundation study (of the costs of the Senate immigration bill) is dominating the immigration news cycle this week. Below are a few reactions to their study:

The nation’s top business and labor groups were near agreement Friday on a guest worker program for low-skilled immigrants, closing in on a deal that would eliminate one of the last significant obstacles to a new proposal for a broad overhaul of immigration laws.

Leading business and union groups announced agreement Thursday on principles to guide talks on immigration legislation, but they failed to resolve some of their most contentious disputes.

Breakthrough agreement would create a new federal bureau to track visas granted to foreign, and often low-skilled, workers.

The AFL-CIO and Chamber of Commerce on Thursday released a set of immigration reform principles, and the press is calling it a breakthrough. But don't be fooled. The real story is that the backroom talks failed, and Big Labor is still holding out for a political commission to run any new guest-worker program.
