Governors File Amicus Brief in Support of Assault Weapons Restrictions and States’ Constitutional Authority To Protect Against Gun Violence
Supreme Court Expected To Hear Oral Arguments on December 2, 2026

As Trump and the MAGAgop advance the “guns anywhere, everywhere” policy – even reversing the commonsense gun safety regulations put forward after the Parkland and Sandy Hook massacres, it is notable that Trump made no comment, completely ignored, the latest school shooting. “Donald Trump and MAGA gun extremists are once again making their fear-mongering and guns everywhere agenda a big part of the 2026 elections. This is a dangerous threat we must take seriously,” writes Everytown.
When the Supreme Court overturned New York State’s century-old gun control law, Governor Kathy Hochul immediately passed legislation to protect New Yorkers while falling within SCOTUS’ new limits.
And while her Republican challenger, Nassau County Bruce Blakeman, has opposed her gun safety legislation and hijacked her success in reducing violent crime and runs on a “public safety, anti-crime” platform, it is Governor Hochul who can claim success in record drops in crime statewide, largely due to Biden-era federal and state funding into prevention programs. She has also built a coalition of states to address the illegal guns that come from “guns-everywhere” permissive states like Florida, and now, she is joining a coalition of governors to urge the Supreme Court to uphold commonsense gun safety laws.
Here’s what’s at stake, according to Everytown:
Assault weapons bans work. When the federal assault weapons ban was in place between 1994 and 2004, it was effective in preventing public mass shootings and reducing the number of fatalities and injuries when these tragedies occurred.
Had it remained in effect from 2005 to 2022, research shows that we could have prevented 38 mass shootings.
11 states and Washington, D.C. have already banned these military–style weapons. And six federal appeals courts have upheld bans on assault weapons and large–capacity magazines as constitutional.
But now, the Supreme Court will decide whether states have the right to ban assault weapons. On December 2, 2026, the justices will hear arguments in Viramontes v. Cook County, a Second Amendment challenge to bans on assault weapons in Connecticut and Cook County, Illinois.
Note: there is no “gun” or “guns” in the Constitution, not even the hallowed Second Amendment, which refers to “well-regulated” “militia” in order to protect the state and “firearms” when “firearm” referred to any weapon carried on the body and the most advanced musket was a single ball. The Founders could hardly have imagined semi-automatic pistols and machine gun-like rifles that could massacre dozens in seconds. – Karen Rubin, editor@news-photos-features.com
Governor Hochul today joined 10 fellow governors in filing an amicus brief with the U.S. Supreme Court in Viramontes v. Cook County and Grant v. Higgins, urging the Court to uphold state and local assault weapons restrictions and preserve states’ constitutional authority to protect their residents from gun violence. Filed through GovAct’s Safer Communities Initiative, the brief argues that state-level assault weapons laws are both constitutional and save lives. Furthermore, the brief lays out the costs that states must bear in the wake of mass shootings — ranging from hospital costs to victim services.
“Combating gun violence is personal to me. Four years ago, I stood with neighbors in my hometown of Buffalo after a hate-fueled gunman used an assault weapon to terrorize innocent New Yorkers. It is unconscionable that our highest court would consider striking down a law designed to keep communities safe from this kind of horror,” Governor Hochul said.“Today, I am joining governors from across the country to remind the Supreme Court of the lives at stake if they choose to dismantle our assault weapons ban, and to fight for our right to protect against gun violence.”
The cases before the Court challenge laws in Connecticut and Cook County, Illinois that regulate certain semiautomatic assault weapons, including AR-15-style rifles equipped with features that increase lethality. A ruling striking down these protections could invalidate lifesaving laws across the country and block states from enacting commonsense public safety measures moving forward.

The amicus brief highlights research demonstrating that assault weapons restrictions can reduce the lives lost to gun violence. One recent study found that counties in states with assault weapons restrictions experienced 41 percent fewer mass-shooting fatalities than counties in states without such protections. Research consistently shows mass shootings involving assault weapons are significantly deadlier than those involving other firearms, leading to more innocent lives lost and families forever changed.
The brief draws on Governors’ firsthand experiences responding to devastating mass shootings. They write: “In the wake of assault-weapon mass shootings, members of the Governors Safer Communities Initiative have stood with grieving families, exhausted first responders, and community members working to rebuild. The safety of our residents is our obligation, and it is at stake.”
The Governors argue that the Constitution has long recognized states’ authority to protect public health and safety, and that elected state leaders must retain the flexibility to enact policies tailored to their communities’ needs.
The Supreme Court is expected to hear oral arguments in the consolidated cases on December 2, 2026. The full amicus brief is available here.
Since taking office, Governor Hochul has committed $4 billion to public safety initiatives including more than $1 billion in gun violence prevention. These investments have contributed to a 67 percent reduction in shooting incidents involving injury over the past five years in the 28 communities participating in the state’s Gun Involved Violence Elimination (GIVE) initiative.
Governor Hochul has also spearheaded significant changes to state firearms laws to help keep New Yorkers safe including: expanding New York’s partnership with 11 other states to intercept weapons along the I-95 corridor, enhancing Red Flag Laws to keep guns away from individuals who are a risk to themselves and others, strengthening New York’s concealed carry laws in response to the Supreme Court’s reckless Bruen decision, and taking action in response to the Trump Administration’s proposed rollbacks that would make sweeping and dangerous changes to federal firearms regulations.
This year, Governor Hochul sustained record-level investments in prevention, intervention and enforcement, including addressing emerging threats such as 3-D printed guns and DIY machine guns. Last week, Governor Hochul signed two additional commonsense gun safety laws to expand firearm safe storage requirements and prevent individuals from purchasing ammunition when they are legally prohibited from purchasing guns.
