WASHINGTON (AP) -- Donald Trump has won the Republican primary in Washington state, helping him inch closer to claiming the GOP nomination for president.

The billionaire businessman’s victory Tuesday pulls him within 44 delegates of the number needed to become the Republican nominee.

Trump won at least 24 delegates in Washington state, with 20 still left to be allocated. He has 1,193 delegates. It takes 1,237 delegates to win the GOP nomination.

There are no more Republican contests until June 7, when the last five states vote. With a total of 303 delegates at stake in California, Montana, New Jersey, New Mexico and South Dakota, Trump should easily clinch the nomination that day.
