Senator Jeff Sessions, a Republican from Alabama, asked on the Senate floor why the body should vote to give majority leader and Nevada Democrat Harry Reid “procedural control” over the debate over the Gang of Eight’s immigration bill. Sessions, speaking Monday afternoon against a motion to close debate on the bill, pointed out that the so-called Corker-Hoeven border security amendment to the immigration bill isn’t really an amendment at all.

“It was filed as a complete substitute to the whole [Gang of Eight] bill,” Sessions said. Reid then moved to invoke cloture on the newly written immigration bill, effectively taking control of the amendment process by not allowing amendments from those senators seeking to offer their own amendments.
