Igor Volsky, executive director at Guns Down America, said that the Biden administration "has simply not done enough" when it comes to gun control issues.
"That's the cycle we're in. We live through a tragedy. We all talk about how sad it is. There's some advocacy, some activism and then we move on," he said.
Early next month, the Supreme Court will consider its first major gun rights case in over a decade.
Volsky said that the court's decision could "expand the meaning of the Second Amendment far beyond frankly what the founders intended."
"The challenge we're in today is actually pushing this administration and Senate Majority Leader Chuck SchumerChuck SchumerHospitals in underserved communities face huge cuts in reckless 'Build Back Better' plan GOP infighting takes stupid to a whole new level Progressive groups urge Schumer to prevent further cuts to T plan MORE to actually live up to the promises they made and to fight for this issue, because otherwise the scene we saw played out in the courtroom yesterday is going to be on repeat over and over and over again across the country," Volsky added.
Volsky's remarks come just one day after Nikolas Cruz, who killed 17 people in a 2018 shooting at Marjory Stoneman Douglas High School in Parkland, Fla., pleaded guilty to all charges he faced.
