(Washington, DC)  --  Washington state's two U.S. senators are calling for Republicans to reverse their pledge not to act once President Obama chooses a nominee to replace Supreme Court Justice Antonin Scalia.  Senator Patty Murray told colleagues that the GOP is politicizing a process that should be above petty partisanship.  Senator Maria Cantwell says the president has a constitutional duty to move ahead with finding a successor.  Following Scalia's death back on February 13th, Senate Majority Leader Mitch McConnell said a successor would not be considered until after the November election.
