BOISE, Idaho (AP) — Idaho Gov. Brad Little has signed legislation aimed at thwarting a half-dozen executive actions taken by President Biden to combat gun violence.

The Republican governor on Monday signed a bill prohibiting Idaho government entities from upholding Biden’s executive actions. The orders include a crackdown on ghost guns — homemade firearms that lack serial numbers used to trace them and are often purchased without background checks.

Biden also tightened regulations on pistol-stabilizing braces like the one used in Colorado in a shooting in March that left 10 dead.

The new state law comes just days after a shooting at a middle school injured two students and a custodian.
