In Texas, Florida, Utah, North Carolina, Iowa and Kentucky, the group, Americans for a Conservative Direction, is airing an ad that features Sen. Marco Rubio (R-Fla.) defending his reform bill.
"Anyone who thinks that what we have now on immigration is not a problem is fooling themselves," he says in a news clip featured in the ad.
A narrator goes on to say that "conservative leaders have a plan," and cites news outlets like McClatchy, CNN and the Washington Post in describing it as "the toughest enforcement measure in the history of the United States," "bold" and "very conservative."
A second ad launched by the group highlights Sen. Lindsey Graham's (R-S.C.) conservative bona fides, an attempt to defend him against a potential challenge from the right.
It showcases clips of Graham criticizing President Obama's health care reform bill, federal stimulus spending and Obama's energy policy.
A narrative urges viewers to "call Senator Graham, tell him to keep fighting for South Carolina" at the end of the ad.
The ads will be backed by seven figures and is the group's first series of advertisements geared towards the ultimate goal of passing immigration reform. Americans for a Conservative Direction has been set up by Zuckerberg's political group, FWD.us, to push reform on the Republican side, according to Politico, which first reported the ads.
Rubio, who's leading the reform effort, and Graham, a member of the bipartisan "Gang of Eight" working on reform, have both come under fire from conservatives opposed to the reform measure released earlier this month.
Graham in particular faces a headache on the issue going into reelection, as conservatives, long dissatisfied with his performance in the Senate, are considering launching a primary challenge against him. The ACD ad looks to improve his standing among conservatives, which could give him more room to act on reform.
