Former House Speaker Newt Gingrich is slated to speak at a high-profile Republican conference with 2012 implications, organizers announced Monday.
The Southern Republican Leadership Conference announced Monday morning that Gingrich will address the event, which takes place April 8-11 in New Orleans. The conference is a major gathering of Republican candidates, donors and activists from 14 Southern states.
The SRLC announced last week that former Alaska governor Sarah Palin, another possible contender for the 2012 GOP presidential nomination, would speak at the event. Minnesota Gov. Tim Pawlenty, also considered a potential White House hopeful, will also speak at SRLC, a source close to Pawlenty confirms to CNN. A senior adviser to Mitt Romney, a 2008 Republican presidential candidate who may make another run in 2012, tells CNN that the former Massachusetts governor will not attend the conference.
