The Latest: Cruz wins endorsement of Missouri Rep. Wagner

Party chairman John Canegata says all nine delegates from the U.S. territory will go to the Republican National Convention as uncommitted delegates.

Democrats and Republicans have painted a dark vision of America, a place where jobs are vanishing, leaders are corrupt and threats loom from across the globe.

Gloomy assessments of the country's future have emerged as a constant refrain of the 2016 presidential contest, as candidates woo a frustrated and anxious electorate.

Republican front-runner Donald Trump says he will defeat the Islamic State group if he is elected president, but he will let the generals "play their own game."

Trump has said he wants to loosen the laws that limit the use of torture if he's elected to the White House, but then appeared to reverse his stance on the use of torture after he was criticized by top Republican national security experts who called his policy views "wildly inconsistent and unmoored in principle."

Former Republican presidential candidate Ben Carson says he and Donald Trump have "buried the hatchet" after months of political wrangling, and he is endorsing the GOP front-runner's White House bid.

Carson warned that it is "extremely dangerous" when political parties attempt to "thwart the will of the people," and urged politicians to "strengthen the nation," rather than create divisions.
