During a closed-door GOP conference meeting earlier that morning, party leaders delivered a more explicit message: Do you side with House Minority Leader Nancy Pelosi (D-Calif.) or President Trump?

Majority Whip Steve Scalise (R-La.), the party’s chief vote-counter, put up a split-screen slide on the wall, according to a GOP source in the room at the Capitol Hill Club. On one side was an image of Pelosi, with a quote saying the GOP healthcare plan “couldn’t be worse.” The other side showed a picture of Trump with a quote saying he was “proud” to support the House GOP repeal-and-replace package.

When this plan moves through the committees and comes to the floor, Scalise told his colleagues, Republicans will have to decide whether to press the red button to vote “nay” or the green button to vote “yea.”

Pelosi will press the red button, Scalise said, according to the source. Trump has made it clear that he wants Congress to put this legislation on his desk, the majority whip added, and that means pushing the green button.
