Governor Bobby Jindal has told Christians at a weekend prayer gathering that the nation needs a spiritual revival.
Outside that gathering at the LSU basketball arena, hundreds protested his appearance.
Jindal as considering a run at the 2016 Republican presidential nomination. He said the rally was a religious event, not a political one.
At the prayer meeting, he talked about his personal Christian conversion, and urged the crowd to plant seeds of faith in everyone they meet.
Former Texas Governor Rick Perry headlined a similar prayer event in 2011 only days before launching his White House bid.
