President Joe Biden is scheduled to reveal a series executive actions aimed at addressing gun violence on Thursday.

This will be Biden’s first time addressing his first major action on gun control since taking office.

He’s also expected to nominate 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.

Biden has faced increasing pressure to act on gun control after a spate 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 expected to announce tighter regulations requiring buyers of so-called “ghost guns” to undergo background checks. The homemade firearms — often assembled from parts and milled with a metal-cutting machine — 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.

Plans for Biden’s announcement Thursday were first reported by Politico.
