See below from FNC’s Mike Emanuel:
The original 6 Senators working on this Senate Immigration effort are: Rubio (R-FL), McCain (R-AZ), Graham (R-SC), Schumer (D-NY), Durbin (D-IL) and Menendez (D-NJ).
I am told Flake (R-AZ) and Bennet (D-CO) have recently joined.
So the bipartisan group is eight – 4 Rs and 4 Ds.
