Lindsey Graham gets air cover on immigration

The ad is the opening salvo in the group's efforts to defend pro-reform Republicans against attacks from the right. South Carolina is shaping up to be an early test on the issue: Graham, who may face a primary challenger, has already been attacked on the airwaves by NumbersUSA, a group that strongly opposes expanding immigration.

The ad, which is running statewide this week, is part of a coordinated effort by different groups in the state to push for immigration reform. The full details of that push will be announced in full later on Wednesday.

"Today's immigration laws are not written for today's South Carolina businesses," Charleston Metro Chamber of Commerce President Bryan Derreberry says in the ad. "South Carolina businesses will not be able to continue to grow without real immigration solutions. Sen. Graham is right on target fighting for immigration reform today. He knows how important it is for South Carolina businesses — he knows that for South Carolina to compete in the 21st century, we have to be able to update our immigration laws. A modern economy needs modern immigration laws, and Sen. Graham gets that."
