Jonah Goldberg thinks that congressional Republicans need to "double down" and work on health care, tax reform and other legislative priorities or they risk losing their majorities in the House and Senate in 2018.

"Donald Trump hasn't gotten a lot of his agenda through, but he at least has stuff he can point to. He's got executive orders, he's repealed a lot of the unilateral stuff that Obama did," Goldberg said on "America's Newsroom." "What has Congress done?"

Bill Hemmer noted that House Freedom Caucus Chairman Mark Meadows (R-NC) has called on Republican leadership to cancel the August recess to continue to work on tax reform and other GOP concerns.

Goldberg pointed out that there are only about 30 legislative days until that scheduled August recess, and in that window, Republicans want to tackle health care, tax reform, the debt ceiling and more.

"There's a lot of big ticket items coming," Goldberg said. "And once you get to 2018, there's not a lot of time for maneuverability because it's an election year."

He said if canceling the August recess is the only way to get those key pieces of legislation through, then Republicans "have no choice."

"If they don't figure how to get their agenda - the agenda that got them elected, often by wider margins than Donald Trump got - they're going to lose in a landslide like in 2006," Goldberg said. "And it is going to be the end of any hope of any serious conservative agenda getting accomplished."
