With 100 percent of precincts reporting on the island, Rubio garnered 73.8 percent of the vote, Trump 13.6 percent, Cruz 9 percent and Kasich 1.4 percent.

Sunday's Puerto Rico primary marks the first time in all of the GOP contests this cycle a candidate has won a majority of the vote. Rubio won all 23 delegates.

Rubio, who campaigned in Puerto Rico Saturday, has now won one state and one territory.

Frontrunner Donald Trump called for Rubio to drop out of the race Saturday night.

"I think it's time for Marco to clean the deck. I do. And I say that respectfully," Trump said.

Puerto Ricans do not vote in presidential elections, but they do participate in the primary process electing delegates for the Republican and Democratic conventions.

In the 2012 GOP primary, Mitt Romney was backed by former Gov. of Puerto Rico Luis Fortuño and earned a whopping 85 percent support compared to second-place finisher Rick Santorum, who garnered 8 percent of the vote.
