Republican Sen. Ted Cruz said congressional Republicans should simply repeal Obamacare and take time to figure out a new replacement bill should they fail to pass new healthcare legislation.

Speaking Sunday on ABC's "This Week," Cruz said the GOP's goal should be to see premiums go down with their new legislation, but if they can't agree on how to do that, they should change their focus to solely repealing Obamacare.

"If we can't get this done right now, I agree with the president, then let's honor the promise on repeal," Cruz said.

He said a repeal would take effect "a year or two years from now" and in that time, Republicans would debate new healthcare legislation.

Even with full control of Congress and the presidency, Republicans have struggled to agree on what a replacement for Obamacare would look like.

President Trump has suggested several times that the GOP may just move on to other policy areas and let Obamacare "explode."
