The Senate cleared a procedural hurdle yesterday on a federal budget compromise. Final congressional approval is expected and could come as early as today. But many Democrats are upset that the budget does not include an extension of unemployment insurance.

Some Democratic lawmakers are pushing a plan to extend the benefits, which they say are a financial lifeline for many families. Opponents argue that an extension would hurt the economy and discourage people from seeking work. A discussion of federal emergency jobless benefits and what’s at stake.
