More than two weeks after he vetoed funding for more than 600 arts and culture grants in Florida, Gov. Ron DeSantis has offered an explanation — citing one production at a festival that he said made the entire event sexually oriented — and depicting himself as a guardian of taxpayers’ priorities and sensibilities. DeSantis pointed to one program put on by one grant recipient, a “fringe festival,” which was in line to receive $7,369 in state matching money as the reason he vetoed $32 million of arts and culture money for organizations throughout the state. Speaking Thursday, DeSantis said there was insufficient oversight and control of the state money that had been going to such organizations.
