House Speaker Richard Corcoran says a special commission is needed to investigate the "abject breakdowns at all levels" that occurred with the mass shooting at Marjory Stoneman Douglas High School in Parkland.
The House, Senate and Gov. Rick Scott will all propose legislation Friday in response to the massacre that claimed the lives of 17 people, including 14 Broward County high school students and three faculty members.
"We want to know every single breakdown," Corcoran said. "We'll use our subpoena power to expose them."
The speaker said a parent of one of the Parkland victims should chair the commission.
The proposal, expected to be part of the House legislative package, gained momentum late Thursday following the revelation that the lone sheriff's deputy assigned to the Parkland school, Scot Peterson, never entered Building 12 during Nikolas Cruz's rampage.
During 15 months as speaker, Corcoran has used the Legislature's power on what he sees as government inefficiency and ineptitude. Past investigations have targeted university foundations, tourism and economic development boards and Visit Florida's contracts to promote the state to tourists.
