Sanford plans to talk to the Greater Anderson Rotary Club on Thursday.
On Wednesday, 61 members of the House Republican Caucus called for Sanford to step down. A day earlier Republican House Speaker Bobby Harrell of Charleston sent Sanford a letter saying he should resign.
Sanford says he is staying. He says the legislators calling for his resignation are the same ones who regularly override his spending vetoes.
At the same time, he's calling on members of civic groups to pressure those legislators to advance his agenda of government restructuring and spending controls.
