 One told me they thought Biden was fragile, and a couple of members also told me they're concerned that Biden and the White House have now dug in. So the challenge here is this could present great political risk for members who do decide to speak out publicly. Now, Democrats will have their regular weekly meeting tomorrow, and they say that's going to be a major test and a chance to decide if they'll all push together for a nominee. And we can say the same for Senate Democrats who are holding their regular meeting tomorrow as well.
