WASHINGTON, D.C. — Sens. Amy Klobuchar and Al Franken today urged the Senate to pass an extension of unemployment and COBRA benefits before the end of the year, citing the 10 percent unemployment rate and the annual rise in heating bills coming this winter. The Minnesota Democrats joined 22 other senators who signed a letter to Senate Majority Leader Harry Reid, asking for a vote on the issue by Dec. 31. A 65 percent subsidy of premium costs for those with COBRA benefits, authorized by the stimulus bill, is set to expire at the end of the year.
