Sorry, I saw similar comments and people saying that finally understands how urgent it is based on CIA briefing (as he said).
The thing is that I don’t buy it. If he really thought it was as important and urgent, he would not split the bill and Biden likely would sign it on the same day, but instead it went back to the Senate.
My belief is that his position was threatened, and if he get replaced (especially if it is true that two Republicans threatened to resign) he won’t be able to block other bills for Biden, because Democrats would control the house.
