Donald Trump hasn’t taken the oath of office yet, but the National Rifle Association is already celebrating the future repeal of gun-free school zones and an end to expanded background checks.

The Associated Press reported over the weekend that gun rights activists were preparing for “a sweeping expansion of gun rights under his administration and a Congress firmly in Republican hands.”

Trump promised during the campaign to end gun-free school zones, roll back President Barack Obama’s expanded background checks and push for nationwide concealed carry reciprocity across state lines.

“This is our historic moment to go on offense and to defeat the forces that have aligned against our freedom once and for all,” NRA CEO Wayne LaPierre said following the election. “The individual right to carry a firearm in defense of our lives and our families does not and should not end at any state line.”

University of California Irvine School of Law Dean Erwin Chemerinsky told the AP that Republicans in Congress might find themselves at odds with backers of states’ rights if they try to force a ban on gun-free zones. Even if Congress repeals the Gun-Free School Zones Act of 1996, states and local municipalities could enact their own bans.

“It would be ironic to see conservatives who long have professed a belief in states’ rights override states’ choices in this area,” Chemerinsky explained.

Experts say that Congress also does not have the authority to force states to recognize out-of-state concealed carry permits.

But when it comes to President Barack Obama’s rule encouraging background checks on Internet guns Ames, Trump can quickly nullify the executive order with the stroke of a pen. Trump is also expected to undo an executive order that allows health care providers to feed mental health information into the federal background check system.

“Baby, those are going into the shredder,” former Gun Owners of America Executive Director Larry Pratt said.
