Senate Majority Leader Harry Reid inched closer to invoking the so-called “nuclear option” in the Senate on Monday, arguing that the body was an “evolving institution” that is stuck in gridlock and needs reform to save it “from becoming obsolete.”

“Flip on C-. … What do you see there the vast majority of the time? Nothing. Blank screens,” Reid said in an address at the Center for American Progress. “We’re wasting time, hour after hour, day after day. … All we have from Republicans … is obstruct and delay.”
