Senate Minority Leader Mitch McConnell and Majority Leader Harry Reid traded floor speeches on Wednesday, accusing the other of partisanship while calling for an end to obstructionism.

The Kentucky Republican criticized the “nuclear option” invoked by the Nevada Democrat in November, but he emphasized he was not trying to “point the finger of blame.”

“My purpose is to suggest that the Senate can do better than it has been and that we must be if we’re to remain as a great nation,” McConnell said. “This is a behavioral problem. It doesn’t require a rules change. We just need to act differently with each other.”
