SAN JUAN, Puerto Rico (AP) — Puerto Rico’s governor pledged Thursday to improve the island’s crumbling electric grid and boost the economy in her first address after being elected last year as anger intensifies over chronic power outages and an increase in cost-of-living expenses. Gov. Jenniffer González Colón, of the pro-statehood New Progressive Party, spoke for nearly two hours as she listed her accomplishments since taking office in January and announced multimillion-dollar investments to improve Puerto Rico’s health, education and public safety.
