Governor Scott Walker wants Wisconsin's attorney general to challenge President Barack Obama's gun control plan.
Walker said in a statement Wednesday that he believes Obama overstepped his authority when he announced an executive action to expand mandatory background checks to gun shows, flea markets and online sales.
Walker says Obama has created uncertainty for law-abiding citizens who want to sell guns and could deprive millions of Americans of their gun rights without any indication of imminent danger.
He called the plan an illegal act.
Walker asked Attorney General Brad Schimel to review the plan as soon as it's released and to take any and all legal measures to challenge it.
Schimel issued a statement saying he's asked his attorneys to review Obama's order and he will determine the next steps.
