Former President Bill Clinton was to have appeared Friday at Meridian Community College, on behalf of his wife and Democratic presidential candidate, Sen. Hillary Clinton.
But the senator's campaign office said Thursday that some emergencies have changed President Clinton's schedule, so the Meridian appearance was bumped to Saturday. His appearance in Hattiesburg was apparently canceled.
The former president is set to campaign Friday in north Mississippi. Bill Clinton will attend a 5:30 p.m. to 7:30 p.m. fish fry at the Tupelo Furniture Mart.
Sen. Hillary Clinton is scheduled to speak Thursday night at a Mississippi Democratic Party dinner in Canton and appear in Hattiesburg Friday.
The Jefferson Jackson Hamer Day Dinner is at 7:30 p.m. at the Canton Multipurpose & Equine Center.
The Barack Obama campaign announced Thursday that the co-founder of the Southern Christian Leadership Conference, the Rev. Joseph Lowery, will attend the dinner and speak on behalf of the Obama campaign.
Sen. Clinton's campaign says she will also appear at a breakfast and town hall meeting from 9 a.m. to 11 a.m. Friday at a train depot in downtown Hattiesburg.
Mississippi is the only state with presidential primaries next Tuesday.
A campaign staff member for Clinton's Democratic rival, Sen. Barack Obama, said Obama plans to campaign in Mississippi Monday, before the primary Tuesday. He will make campaign stops in Columbus and Jackson. Obama last visited the state in June 2007.
