Rep. Matt Cartwright asked Attorney General William Barr about the Affordable Care Act, which the Trump administration recently said should be struck down.

Barr said he wants to let the courts "do their job" when it comes to the lawsuit.

Here's how the exchange went down:

CARTWRIGHT: Let me be the one to inform you that should the law be struck down, millions of people who get their coverage through the ACA marketplace would lose their coverage, and tens of millions more would see their premiums skyrocket. In addition if you are successful, 12 million people nationally and 750,000 in my home state of Pennsylvania who have coverage under the Medicaid expansion would also likely lose that coverage. Am I correct in that, sir?

BARR: I do think it’s likely we’re going to prevail.

CARTWRIGHT: If you prevail — well, you’re devoting scarce resources of your department to that effort, are you not Attorney General?

BARR: We’re in litigation — we have to take a position — we take position in litigation...

CARTWRIGHT: The answer is yes. You are trying to get it invalidated and if you succeed, that many people will lose their coverage nationally from Medicaid, and 750,000 from Pennsylvania alone, right?

BARR: I’m just saying, if you think it’s such an outrageous position, you have nothing to worry about. Let the courts do their job.
