Donald Trump will not give a definitive blanket endorsement to the House GOP's Obamacare replacement plan in his speech to Congress tonight, according to sources familiar with the speech. The view internally is that the current plan — drafted by both House and Senate leadership — is going to struggle to get out of Congress. It would be foolish for Trump to walk all the way down the plank and utter the sentence: "I support the health care plan drafted by the House."
What Trump is expected to do: Signal a receptivity to the House plan, especially to the key concept of tax credits. This is a win for House and Senate leadership, especially Speaker Paul Ryan.
