Shutting down the government over Obamacare hurt Republicans and gained nothing, billionaire Home Depot founder Ken Langone told CNBC on Wednesday.
Describing himself as a "loyal, enthusiastic Republican," Langone took to task House Republican Policy Committee Chairman James Lankford of Oklahoma during a "Squawk Box" interview.
"Congressman, help me out," Langone said. "What the hell did you guys gain by shutting the government down other than to get a black eye for all of us?"
Lankford, also a Budget Committee member, responded, "I would agree. We got a black eye on it. The problem that we have is we overreached."
