Asked about the "widely optimistic" outlook for economic growth in the Trump administration's budget, House speaker Paul Ryan seemed uncertain of the specifics, but said he has confidence in the Office of Management and Budget:

"I haven't seen the details yet, I don't want to get ahead of [Mick] Mulvaney... but I would say this ... we never hit 3% growth in the last presidency at all... the problem for us as Americans is that we have embraced slow growth strategies for the last eight years and now we have an administration and Congress committed to pro-growth strategies.
"Whether or not we hit those numbers, I don't know the answer yet because I haven't seen all of those numbers, but I would expect that OMB will put their projections of what the economy will reach in their budget."
