The incoming House Budget Committee chairman said Sunday that Republicans are going to get to work cutting spending in order to cut the deficit in the next Congress.

Paul RyanPaul Davis RyanEmbattled Juul seeks allies in Washington Ex-Parkland students criticize Kellyanne Conway Latina leaders: 'It's a women's world more than anything' MORE (R-Wis.), appearing on "Fox News Sunday," said that the first order of business will be doing "what the Democrats didn't do. We're going to cut spending."

"I find it sort of interesting that after this massive spending spree that took place over the last two years, the creation of two new healthcare entitlements, now there's concern about deficits when they have a chance of raising taxes," he said, stressing that the majority of the tax deal was about keeping rates where they are, but panning the other $313 billion in spending add-ons.

"We're going to come out of the gates going after spending ... spending cuts, spending controls, reforms of the structure of spending," Ryan said.

"And if we get to the point of doing tax reform, which I think is an important way to go, we should go with broader-based lower rates for economic growth," he said.

Ryan encouraged centrist Democrats to get on board "good pro-growth tax reform."
