Retired neurosurgeon Ben Carson has released the two delegates he won in the Nevada caucuses, meaning they are now free to support whichever candidate they choose at the Republican National Convention in July, CNN reported.

The state allocates delegates proportionally, giving him two of the 30 delegates at stake.

On Friday, Carson sent a letter to the Nevada Republican Party asking that his delegates be released from supporting him.

He had the choice to release his delegates or to let the party reapportion them based on the percentage the remaining candidates won in the state. 

Trump, who is getting closer to clinching the nomination, won about 46 percent of the vote in the state, securing 14 delegates, according to The Associated Press. Sen.

Next weekend, grassroots activists and party insiders will decide who will serve as delegates from Nevada. Carson's two released delegates could go to Trump if the front-runner gets enough of his backers elected as delegates in the state.

Trump needs 1,237 delegates to clinch the nomination and avoid a contested convention. His next opportunity to advance toward that goal is Tuesday, when Indiana votes in its primary.
