The Senate’s two immigration fighters clashed Wednesday, with Republican Sen. Jeff Sessions dismissing New York Sen. Chuck Schumer’s immigration reform legislation, known as the “Gang of Eight,” as amnesty.

At a hearing about the negative impact immigration has on the wages of native-born Americans, Schumer claimed that his bill was “not amnesty, not amnesty.” He also blamed the Tea Party for playing a leading role in killing the legislation, once backed by Florida Sen. Marco Rubio, who bowed out of the presidential race Tuesday night.
