Ryan's office on Monday even took the public step of refusing to the possibility that the Speaker might drop his endorsement of Trump.
"There is no update in his position at this time," a spokesman told reporters.
Those comments did not sit well with Trump's team, as a campaign spokeswoman made clear that some Trump backers might not pull the lever for Republicans running for Congress this year.
It's that possibility that has GOP lawmakers who are running for the House and Senate worried, that if Trump loses big in November, he might take them down the tubes as well.
And it wasn't hard to find ready-made examples of that on social media, as strong supporters of Trump see Ryan and others as expendable.
The infighting could not only hurt Republican efforts to hold on to the Senate, but some worry there could be a big spillover effect on the House of Representatives.
Asked about the party's internal battle over Trump, one GOP member of Congress told me on Monday that the GOP is "Lost in Space."
Four weeks from today, we'll know if the Republicans can keep control of the Congress; right now, they are not all on the same page.
