A New York lawmaker is going after bad Santas with a bill that would require costumed characters who work with children to undergo background checks before getting hired.

The bill, introduced this week by state Sen. James Skoufis (D-Rockland), would apply to mall Santas, Easter bunnies and other characters who are hired by employers to play their parts.

Employers would have to screen the prospective workers to ensure they are not on the state or national sex offender registry.

Hiring a known sex offender would be a class-A misdemeanor.

“There’s a list, it’s time we check it twice,” Skoufis said in a statement. “It’s shocking to me that this isn’t law already.”

“New York needs to keep our communities safe by requiring background checks for these individuals interacting with children because our families deserve nothing less,” he said.

If the bill becomes a law, it would take effect the November after it’s signed.
