House Speaker Paul Ryan said Thursday that Republican lawmakers will try to push through tax reform and infrastructure bills — two key policies for investors — in the spring after focusing on health care.

"It's just the way the budget works that we won't be able to get the ability to write our tax reform bill until our spring budget passes, and then we write that through the summer," Ryan said on "Fox and Friends."

He added that an infrastructure package "comes out of our spring budget, as well."

Hopes for corporate tax cuts and spending on infrastructure projects helped to power the stock market after President Donald Trump won the White House and Republicans kept control of both chambers of Congress in November. However, other issues like immigration and repeal of the Affordable Care Act have largely consumed Trump and GOP lawmakers in the early days of the new administration.

"We feel the need to rescue this system here and that's why we're going with health care first, that's the first budget. And then in the spring we're doing the second budget. That's where tax reform comes," Ryan said.
