Sen. Thom Tillis (R-N.C.) argued it is “immoral” for Republicans to reject a border deal to help former President Trump.

“I didn’t come here to have the president as a boss or a candidate as a boss. I came here to pass good, solid policy,” Tillis said Thursday, first reported by NBC News. “It is immoral for me to think you looked the other way because you think this is the linchpin for President Trump to win.”

Members on both sides of the aisle are upset with Trump’s attempt to kill the border deal to deny President Biden a legislative win. His recent remarks calling for GOP members to oppose a border deal that isn’t H.R. 2 have complicated things for the Senate.
