What Lankford, Flake and Corker want before voting on the tax bill

Republican senators James Lankford (Okla.), Bob Corker (Tenn.) and Jeff Flake (Ariz.) want a tweak to the tax bill which would allow changes to be made if in 5 years the plan doesn't produce the economic growth Republicans are banking on, Lankford told Hugh Hewitt on Tuesday. He said that if their proposal is added, the three would most likely vote yes on the bill, although he didn't want to speak for Flake and Corker.

Why it matters: Flake and Corker have become wild cards since announcing they won't run for re-election, and both have expressed reservations about the GOP tax bill. But the "changes" in 5 years would most likely include tax hikes, which could be unpopular with the public and President Trump who has always touted across-the-board tax cuts.
