Senate Minority Leader Mitch McConnell cautioned President Barack Obama Wednesday about taking widely expected unilateral moves on immigration while laying out agenda items for the lame-duck session.

“There’s a lot both parties can accomplish together over the next couple years. I hope that happens. I’m optimistic. But working together requires trust,” McConnell said on the floor. “I think President Obama has a duty to help build the trust we all need to move forward together, not to double-down on old ways of doing business.”

“That’s why I think moving forward with the unilateral action on immigration he’s planned would be a big mistake,” McConnell said.
