Four Republicans voted to bring an unemployment benefits extension to the floor last week but then voted to filibuster the bipartisan deal on Wednesday.
Dan Coats of Indiana, Bob Corker of Tennessee, Ron Johnson of Wisconsin and Patrick J. Toomey of Pennsylvania all voted Wednesday to block the bipartisan agreement led by Sens. Jack Reed, D-R.I., and Dean Heller, R-Nev.
Joining Democrats to pass the bill were Kelly Ayotte of New Hampshire, Susan Collins of Maine, Dean Heller of Nevada, Mark S. Kirk of Illinois, Lisa Murkowski of Alaska and Rob Portman of Ohio. They helped put the measure over the top, narrowly topping the 60-vote threshold, 61-38.
Final passage could be as early as Thursday.
