Former U.S. Sen. Rick Santorum of Pennsylvania is scheduled to appear Wednesday at campaign rallies in Tupelo and in Jackson. On Sunday, he will appear at a rally in Meridian at Weidmann's, and also a rally in Gulfport.

Tuesday, the Mississippi GOP listed a more specific agenda for Santorum:

Former U.S. Rep. Newt Gingrich of Georgia is scheduled to appear Thursday in Jackson, Tupelo and Southaven. He's also doing a $250-per-person fundraiser that day at a Jackson restaurant.

On March 12, Gingrich and Santorum are set to appear at the Gulf Coast Energy Summit in Biloxi.

Former Massachusetts Gov. Mitt Romney will decide later whether to make appearances in Mississippi. That's according to Austin Barbour of Jackson, one of his national finance chairmen.
