Puerto Rico Governor Loses Primary to Former Ally

Gov. Pedro R. Pierluisi of Puerto Rico lost his bid for a second term on Sunday, suffering a rare defeat by a sitting governor on the island after a rancorous primary.

Mr. Pierluisi was defeated by Representative Jenniffer González-Colón, Puerto Rico’s nonvoting member of Congress, in the primary for the governing New Progressive Party, which supports Puerto Rican statehood, The Associated Press reported.
