Israel has come under heavy criticism for his agency's response to last February's school shooting at Marjory Stoneman Douglas High School in Parkland.
DeSantis confirmed Israel's suspension at a news conference just before 5 p.m. at the headquarters of the Broward sheriff's office in Fort Lauderdale.
DeSantis has been under pressure to remove Israel. Andrew Pollack, whose daughter died in the shooting, was a member of DeSantis' transition team and said Tuesday that Israel should be suspended for failing to protect the students.
