Story highlights Donald Trump has now reached the threshold of 1,237 delegates to clinch the Republican presidential nomination

He becomes the official nominee once delegates cast their votes on the convention floor in July

(CNN) Donald Trump has the delegates to clinch the GOP presidential nomination, according to a CNN delegate count Thursday.

While Trump has had the nomination locked down for weeks, he has now reached the threshold of 1,237 delegates with the help of previously uncommitted delegates who now support his candidacy.
