DeMint placed himself at the center of the fight over the last comprehensive immigration reform bill in 2007, leading a conservative Republican faction against the bipartisan effort supported by President George W. Bush and dozens of congressional Republicans and Democrats.

"If [Bush] continues to push this bill in spite of the way the American people feel about it, I think that's more likely to undermine him,'" DeMint told CNN in June 2007.

"In early 2007 DeMint also fought for common-sense immigration reform by leading the effort to defeat the amnesty bill and calling on government to first secure our borders, enforce the laws already passed, and streamline the legal immigration system," reads his official Senate biography.
