If Rosselló's choice for a secretary of state is not approved by the island’s House and Senate, Puerto Rico’s law dictates the treasury secretary would be next in line if the justice secretary doesn’t become governor. But current Treasury Secretary Francisco Parés is too young at 31 years old. The constitution dictates the person would have to be at least 35, so that would leave interim Education Secretary Eligio Hernández next in line. He replaced former education secretary Julia Keleher, who resigned in April and was arrested July 10 on federal corruption charges. She has pleaded not guilty.
