President Joe Biden is expected to roll out new executive steps today that tighten gun control.
Biden's announcement comes amid growing concern about gun violence and untraceable "ghost guns" that can be 3D-printed at home.
Two sources told NBC News that the administration hopes to "rein in" the pandemic wave of firearms-related attacks.
Biden is also expected to name a new and long-awaited replacement nominee to lead the Bureau of Alcohol, Tobacco, Firearms and Explosives.
