Rep. Thomas Massie (R-KY) blasted his own party Thursday, arguing Republicans are squandering their majority and warning they could face a “shellacking” in the November midterm elections if they fail to deliver on their agenda.

“The problem is we’re wasting our opportunity that the voters gave us,” Massie told reporters outside the Capitol building. “And the Republicans are going to pay for that in November. It’ll be an absolute shellacking if they don’t wake up.”
