By rushing, Kyl said, Democrats were letting populist outrage trump informed decision-making in the Senate, which is supposed to be insulated from the pressures of public passion.

“I don’t believe that Congress should rush to pass yet another piece of hastily crafted legislation in this very toxic atmosphere, at least without understanding the facts and the potential unintended consequences,” Kyl said on the Senate floor. “Frankly, I think that’s how we got into the current mess.”

Senate Democrats said they will try again next week to take up the tax bill and hope to complete it before April 4, when Congress leaves for a two-week spring break. Combining the disparate House and Senate versions of the bill might have to wait until after the recess.

The Senate voted last month to block the bonuses at AIG and other companies as part of the $787 billion stimulus bill, but Democrats then watered down the measure allowing them after Treasury Department officials warned that the move could trigger lawsuits against the government.
