SAN JUAN, Puerto Rico (AP) — The Latest on Puerto Rico's referendum on its political status. (all times local):

5:45 p.m.

Puerto Rico's governor says the U.S. territory has overwhelmingly chosen statehood in a non-binding referendum.

Ricardo Rossello said Sunday that the island has sent a strong and clear message to U.S. Congress and the world.

Nearly half a million votes were cast for statehood, more than 7,600 for free association/independence and nearly 6,700 for the current territorial status. The participation rate was nearly 23 percent with roughly 2.26 million registered voters.

But many question the validity of the vote amid a low turnout and a boycott by several opposition parties.

U.S. Congress has final say on any changes to the U.S. territory's political status, regardless of the referendum's final outcome.
