I thought they were wanting to raise the minimum wage not devastate it?

On Friday, Sen. Jeff Sessions (R-AL) said the House was the last line of defense for the millions of Americans whose wages and livelihood will be put at risk by amnesty and comprehensive immigration reform.

He urged House Republicans to put the interests of American workers ahead of those of the consultant class, lobbyists, and Democrats who want cheaper labor and more potential votes.

House Republican leaders are preparing to unveil their “immigration principles” which will include amnesty provisions that the Congressional Budget Office determined would lower the wages of American workers. Sessions, the ranking Member of the Budget Committee, said that Obama and Senate Democrats have “uniformly embraced an immigration plan that would devastate wages and working conditions for millions of struggling Americans to benefit a small cadre of lobbyists and CEOs.”
