Sen. Chuck Schumer laughed about Florida Republican Marco Rubio’s collaboration on the Gang of Eight immigration bill on Thursday, as he debated the merits of the legislation with Sen. Jeff Sessions, R-Ala.

The New York Democrat argued that Sessions’ hearings on immigration demonstrate the need for the Gang of Eight legislation that stalled in the last Congress. He listed the Republican senators who helped draft the bill, saving Rubio for last and putting special emphasis on his name. Then Schumer said the lawmakers worked “on the Democratic — on the Republican side” to pass the bill.
