I don’t know if Trump worked on it with Ryan or not. I do know Trump almost immediately said he was looking forward to Sen. Paul’s bill so he’s clearly looking for significant changes.
If Trump is willing to work with Rand Paul, that is very good news.
Trump is fully aware he has a split in the Republican party over healthcare. He wants a united team so he’s not going to chastise anyone publicly, but he knows the current Ryan bill would lose in a House vote with many Republicans joining all of the Democrats.
