WASHINGTON — President Barack Obama is slated Monday to finalize a set of new executive actions tightening the nation’s gun laws, making his first order of business in 2016 a clear signal the president in his final year doesn’t intend to go quietly.

At a meeting with Attorney General Loretta Lynch, FBI Director James Comey and other top law enforcement officials Obama is expected to sign off on a package of proposals aimed at curbing gun violence and cracking down on unregulated gun sales.

At the top of the list is an effort 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 unregistered sellers who skirt the background check laws by selling at gun shows, online or informal settings. Other moves being considered include improving reporting of lost and stolen weapons and beefing up inspections of licensed dealers, according to a person familiar with the plans who would not be named discussing proposals before they are finalized.

The package includes measures this White House has long considered but not completed, mindful of the legal fight sure to follow as well as the potential for political backlash for some fellow Democrats.

But after a steady string of mass shootings and with the clock on his tenure ticking down, Obama appears primed to push further than he has in the past.
