Florida Sen. Marco Rubio has won Puerto Rico’s Republican primary, his second win of the race for the GOP presidential nomination.

It wasn’t clear how many delegates the contest awards him.

The U.S. territory’s three super-delegates have committed to Rubio.

If a candidate gets more than half the votes, he gets all the delegates. If no one gets half, the delegates are divided proportionally.

There are 23 delegates at stake.

Rubio so far has 2,463 votes, followed by Trump with 421 votes and Ted Cruz with 276 votes. Final results are expected by 8 p.m. EST. Party officials estimate more than 30,000 people voted Sunday.

In addition officials say the votes that some 6,000 inmates cast on Friday won’t be available until Wednesday.

Rubio also won Minnesota.
