After good news last week that the Senate would be unveiling its version of a climate bill at the end of the month—even though “Senate compromises frighten, infuriate some enviro groups“—there are indications that Congress may punt on the legislation this year to tackle immigration. Happy 40th Earth Day!

Weekend Updates:
Republican Senator Graham withdrew support from the bill, and Senator Kerry subsequently delayed the bill which was scheduled for release on Monday. However, the senior Massachusetts Senator says the bill is not dead, Senator Lieberman reports that Graham may yet again get behind the legislation he helped craft if Reid paves the way for the more advanced climate bill rather than open yet another can of worms. Tuesday evening Reid he is willing to tackle climate first, but not to the satisfaction of Graham. Given these issues, some have suggested that it might be time to instead focus on the Bingham bill, however it’s likely to experience hiccups of its own.
