 Puerto Rico does not have a post for lieutenant governor but the Chief of Staff performs a similar role as the officer charged with managing and overseeing all executive agencies.The Chief of Staff, however, is not empowered to act as acting governor—the Constitution of Puerto Rico and Puerto Rican law establishes a governmental line of succession starting with the Secretary of State.Article IV of the Constitution of Puerto Rico establishes that the Secretary of State should serve as acting governor when the Governor is not available.
