A 16 member commission designed to address school safety is now down to 15.
Andrew Pollack, who lost his daughter February 14th, announced he resigned from that commission Thursday.
He still supports the commission.
"I know the commission is going to do what they have to do," said Pollack.
He says he wants to focus on the upcoming school board election and also wants to focus on his independent investigation.
Andrew has been critical of school leaders and the sheriff's office.
"My daughter was murdered that day and I'm never going to see my kid again and that I something that I take serious what they allowed to happen," said Pollack.
Pollack also continues with his movement to improve school safety across the country.
The Marjory Stoneman Douglas High School Public Safety Commission meets again tomorrow at the BB&T Center in Sunrise.
The commission's 15 members will report their findings to Gov. Rick Scott and make recommendations for preventing future shootings.
