Senate Majority Leader Mitch McConnell, R-Ky., said he's confident both houses of Congress will be able to reach a deal to pass sweeping tax cuts now that each has passed their own versions.

Reacting to the Senate passing its own bill this weekend, McConnell said Sunday on ABC's "This Week" that getting a final bill through both chambers is essentially a done deal.

"Yeah, we’ll be able to get to an agreement in the conference," he said. "I’m very optimistic about it. We think this will make a big difference in getting our economy moving again and providing jobs and opportunity for the American people."

McConnell rebuked critics who say the tax cuts in the Senate's bill balloon the federal deficit, saying economic growth spurred by the cuts will naturally drive revenue to the government.

"I’m confident that this is not only revenue neutral to the government but actually is very likely to be a revenue producer for the government," he said.
