(WASHINGTON, D.C) — Some gun violence prevention groups said Wednesday that they plan to double down in their fight for stronger firearm-control laws in the wake of former President Donald Trump recapturing the White House and promising to roll back President Joe Biden’s efforts to curb the national plague.

During his victorious campaign, Trump and his running mate, Sen. JD Vance, voiced opposition to most of Biden’s executive orders to combat the scourge that the Johns Hopkins Center for Gun Violence Solutions found to be the leading cause of death in the United States for adolescents under the age of 19 for three straight years.

“The election of Donald Trump is deeply troubling for our safety and freedom from gun violence,” Kris Brown, president of the Brady Campaign to Prevent Gun Violence, said in a statement Wednesday. “And that’s why we are doubling down on our work and fighting harder than ever.”

Gun violence was a big issue during the campaign. In an ABC News/Washington Post/Ipsos poll released in August, gun violence was ranked eighth in importance among voters after the economy, inflation, health care, protecting democracy, crime and safety, immigration and the Supreme Court.

In preliminary national exit polls analyzed by ABC News, voters said they trusted Trump over Vice President Kamala Harris, 50% to 48%, in handling the issue of crime and safety.

In his campaign, Trump often railed against what he described as a “surge” in migrant crime, including several high-profile homicides allegedly committed by undocumented immigrants. A 2020 study in the Proceedings of the National Academy of Sciences found U.S.-born citizens are over 2 times more likely than migrants to be arrested for violent crimes.

Brown said it won’t be the first pro-gun rights administration that has occupied the White House, adding that Trump’s previous four years in the Oval Office were marked by a “deadly period for Americans.” Among the mass shootings that occurred during Trump’s first term was the 2017 massacre at the Route 91 Harvest Festival music concert in Las Vegas that left 58 people dead and more than 850 people wounded; the 2018 mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, that killed 17 students and staff; and the 2019 shooting at a Walmart in El Paso, Texas, that claimed 23 lives and injured nearly two dozen other people.

“So even though we won’t have a friend in the White House, Brady isn’t giving up an inch,” Brown said of her organization named after White House press secretary James “Jim” Brady, who was shot and permanently disabled in the 1981 assassination attempt on then-President Ronald Reagan and later died in 2014 as a result of his wounds.

Brown added, “The movement to prevent gun violence has always been larger than one office, and we’ll continue to work with activists, survivors, community leaders and elected officials in states across the country to fight for progress that makes the whole country safer from gun violence.”

Trump and Vance, who have said they oppose a national ban on assault weapons, were endorsed by the National Rifle Association (NRA).

In February, Trump told NRA members at a forum in Harrisburg, Pennsylvania, “No one will lay a finger on your firearms” during his second term in office.

“During my four years, nothing happened and there was a lot of pressure on me having to do with guns,” Trump said at the time. “We did nothing, we didn’t yield. And once you yield a little bit that’s just the beginning, that’s [when] the avalanche begins.”

In May, Trump spoke at the NRA convention in Dallas and outlined some of the actions he’ll take in his second term.

“In my second term, we will roll back every Biden attack on the Second Amendment — the attacks are fast and furious — starting the minute that Crooked Joe shuffles his way out of the White House,” Trump said in the speech.

Trump also vowed during the speech to fire Steven Dettelbach, the director of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). House Republicans have also said they want to abolish or drastically cut funding for the ATF.

“At noon on Inauguration Day, we will sack the anti-gun fanatic Steve Dettelbach,” Trump told NRA conventioneers. “Have you ever heard of him? He’s a disaster.”

Gun control advocates said they expect Trump to try to water down the Bipartisan Safer Communities Act (BSCA), the first major gun safety law enacted in 30 years that Biden signed in June 2022, about a month after a teenage gunman killed 19 students and two teachers at Robb Elementary School in Uvalde, Texas. The BSCA enhances background checks for gun buyers under 21, closes the so-called “boyfriend loophole” to prevent people convicted of domestic abuse from purchasing guns, and allocates $750 million to help states implement “red flag laws” to remove firearms from people deemed to be dangerous to themselves and others.

Advocates also expect Trump to abolish the first White House Office of Gun Violence Prevention established under the Biden administration and overseen by Harris.

Angela Ferrell-Zabala, executive director of Moms Demand Action released a statement on social media Wednesday, saying her gun violence prevention group also plans to continue to fight for laws that protect Americans from gun violence.

“If this work has taught me anything, it’s that no matter what, we always can and will secure victories to protect our communities from gun violence. This obstacle is no different. Today, we are crushed by this result,” Ferrell-Zabala said of Trump’s victory. “Tomorrow, we’re going to continue to organize like our lives depend on it — because they do.”
