WASHINGTON (AP) – President Barack Obama is slated to finalize a set of new executive actions tightening the nation’s gun laws.

At a meeting with Attorney General Loretta Lynch, Obama is expected to sign off on a package of proposals aimed at curbing gun violence and cracking down on unregulated gun sales.

The package includes a proposal to expand background checks on gun sales by forcing more sellers to register as federally licensed gun dealers. The changes would be aimed at some sellers who skirt the background check laws by selling at gun shows or informal settings. Another proposal being considered would improve reporting of lost and stolen weapons, according to a person familiar with the plans.

Gun rights groups are likely to challenge the proposals in court.
