Following a deadly shooting at Florida State University on Thursday, the president of the American Federation of Teachers, Randi Weingarten, vowed to redouble the union’s efforts to push for gun safety reform.

“Campuses and classrooms must be safe and welcoming places, but they can become unsafe in an instant because of the ever-present threat of gun violence,” said Weingarten, who noted that the shooting at FSU comes on the heels of a shooting at a Dallas, Texas high school on Wednesday and a shooting near a school campus in San Antonio, Texas also on Wednesday.

“We are the only country in the world that regularly deals with this—but we don’t have to live this way,” Weingarten said. “We should remove weapons of war from our streets and communities, fund community violence intervention programs, enforce background checks and safe-storage laws, ban high-capacity magazines, and pass more risk-protection laws.”

“Lawmakers must urgently move to thwart these horrific events that result in terrifying and tragic real-world consequences,” Weingarten concluded.

In a press conference Thursday afternoon, FSU Chief of Police Jason Trumbower said that two people are dead following the shooting—though they were not students. Six others were wounded. The gunman was also shot and is at the hospital.

CNNreported that the shooting suspect has been identified as 20-year-old Phoenix Ikner, who is the son of a Leon County sheriff deputy.

Fred Guttenberg, whose daughter was killed during the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida in 2018, said he is not surprised by the shooting at FSU and that some of his daughter’s friends are currently attending FSU.

“My daughter Jaime was murdered in the Parkland school shooting. Many of her friends who were lucky enough to survive that shooting went on to attend FSU. Incredibly, some of them were just a part of their 2nd school shooting and some were in the student union today,” he wrote on X.

The Tallahassee Democrat also reported that a survivor of the Parkland school shooting was at the FSU campus Thursday.

The gun violence prevention group Giffords reacted to the news of the shooting, writing on X: “What Florida doesn’t have: Universal background checks, assault weapon restrictions, large-capacity magazine bans. What Florida does have: The latest school shooting in America.”
