 The events over the weekend have created some changes to convention programming and operations. Former South Carolina Governor Nikki Haley, who initially was not invited to the RNC, is now slated to speak on Tuesday at the convention. The U.S. Secret Service in a statement ahead of the start of the convention said that the security plan for the convention has been reviewed and strengthened in the wake of Saturday's shooting.
