WASHINGTON (NewsNation Now) — The Biden administration announced a series of executive actions aimed at addressing gun violence Thursday, including a new rule combatting “ghost guns” and publishing “red flag” legislation for states to adopt.

“Gun violence in this country is an epidemic and international embarrassment,” Biden said during remarks at the White House. “Whether congress acts or not, I’m going to do everything I can to protect the American people.”

Greeting the families of gun violence victims and activists, he assured them: “We’re absolutely determined to make change.”

His Thursday announcement delivers on a pledge Biden made last month to take what he termed immediate “common-sense steps” to address gun violence, after a series of mass shootings drew renewed attention to the issue. His announcement came the same day as yet another shooting, this one in South Carolina, where five people were killed.

His announcement underscores the limitations of Biden’s executive power to act on guns. They include moves to tighten regulations on homemade guns and provide more resources for gun violence prevention but fall far short of the sweeping gun-control agenda Biden laid out on the campaign trail.

Biden has faced increasing pressure to act on gun control after a string of mass shootings across the U.S. in recent weeks, but the White House has repeatedly emphasized the need for legislative action on guns.

While the House passed a background-check bill last month, gun control measures face slim prospects in an evenly-divided Senate, where Republicans remain near-unified against most proposals.

Biden is tightening regulations of buyers of “ghost guns” — homemade firearms that usually are assembled from parts and milled with a metal-cutting machine and often lack serial numbers used to trace them. It’s legal to build a gun in a home or a workshop and there is no federal requirement for a background check. The goal is to “help stop the proliferation of these firearms,” according to the White House.

The Justice Department will issue a proposed rule aimed at reining in ghost guns within 30 days, though details of the rule weren’t immediately issued.

A second proposed rule, expected within 60 days, will tighten regulations on pistol-stabilizing braces, like the one used by the Boulder, Colorado, shooter in a rampage last month that left 10 dead. The rule will designate pistols used with stabilizing braces as short-barreled rifles, which require a federal license to own and are subject to a more thorough application process and a $200 tax.

White House press secretary Jen Psaki said last month, however, that executive actions on guns were coming as well, calling them “one of the levers that we can use” to address gun violence.

As a part of Biden’s executive actions, he will have the AFT and Justice Department issue an annual report on firearms trafficking. The last report was issued in 2000 and does not account for things like “ghost guns” according to the Biden administration.

Some states, like California, have enacted laws in recent years to require serial numbers be stamped on ghost guns.

The critical component in building an untraceable gun is what is known as the lower receiver, a part typically made of metal or polymer. An unfinished receiver, sometimes referred to as an “80-percent receiver”, can be legally bought online with no serial numbers or other markings on it, no license required.

A gunman who killed his wife and four others in Northern California in 2017 who had been prohibited from owning firearms built his own to skirt the court order before his rampage. And in 2019, a teenager used a homemade handgun to fatally shoot two classmates and wound three others at a school in suburban Los Angeles.

To counteract community violence, the Biden administration will work with five federal agencies to make changes that curtail force. He also highlighted that the American Jobs Plan will include a $5 billion investment over eight years in community violence intervention programs.

The department also will begin to provide more data on firearms trafficking, starting with a new comprehensive report on the issue. The administration says that hasn’t been done in more than two decades.

Biden also nominated David Chipman, a former federal agent and adviser at the gun control group Giffords, to be director of the Bureau of Alcohol, Tobacco, Firearms and Explosives.

The Biden administration will also make investments in community violence intervention programs, which are aimed at reducing gun violence in urban communities, across five federal agencies.

Officials said the executive actions were “initial steps” completed during Garland’s first weeks on the job and more may be coming.

The ATF is currently run by an acting director, Regina Lombardo. Gun-control advocates have emphasized the significance of this position in enforcing gun laws, and Chipman is certain to win praise from this group. During his time as a senior policy adviser with Giffords, he spent considerable effort pushing for greater regulation and enforcement on ghost guns, changes to the background check system and measures to reduce the trafficking of illegal firearms.

Chipman spent 25 years as an agent at the ATF, where he worked on stopping a trafficking ring that sent illegal firearms from Virginia to New York, and served on the ATF’s SWAT team. Chipman is a gun owner.

He is an explosives expert and was among the team involved in investigating the Oklahoma City bombing and the first World Trade Center bombing. He also was involved in investigating a series of church bombings in Alabama in the 1990s. He retired from the ATF in 2012.
