The Consumer Product Safety Commission is looking into whether Fisher-Price let the agency know as quickly as it should have about lead paint found in 1.5 million Chinese-made toys that were recalled worldwide last week.

Scott Wolfson, a spokesman for the commission, told The Associated Press on Monday that it was conducting “an active and open” investigation into the timing of Fisher-Price’s disclosure. He declined to provide details, including when Fisher-Price notified authorities of the problem.
