CHEYENNE, Wyo. — Ted Cruz has nailed down all 14 Wyoming Republican delegates up for grabs at the state party convention Saturday, leaving Donald Trump facing yet another loss in a string of defeats in Western states.

Saturday's sweep follows Cruz's victory last month in Wyoming, when he scored 9 of 12 available delegates at county conventions.

Trump and Marco Rubio each won 1 delegate last month in Wyoming while one remained undecided.

Cruz was the only candidate to address the convention crowd Saturday in Casper, promising to end what he called President Barack Obama's “war on coal” if he's elected. Wyoming, the nation's leading coal-producing state, has seen hundreds of coal industry layoffs in recent months.

Trump still leads the overall delegate race with 744; Cruz, 559; and John Kasich, 144. A GOP candidate needs 1,237 delegates for the nomination.

On the Democratic side, Hillary Clinton, in California for fundraisers, lauded the state Saturday for what she called leadership on a host of issues, including raising the minimum wage and increasing compensation for those taking paid family sick leave.

Clinton, the favorite to win New York's primary Tuesday against Bernie Sanders, noted that New Yorkers recently passed similar measures.

“Let's take California values and New York values and put them to work for American values,” she said to thunderous applause from dozens of supporters at Los Angeles Southwest College.

Meanwhile, Sanders picked up a few extra delegates at Colorado's Democratic state convention.

Colorado has a multistep process of allocating delegates.

Based on the March 1 caucus, Sanders initially picked up 38 delegates to Clinton's 28.

Since then, Sanders has won additional support at congressional district conventions and Saturday's state convention, resulting in a few more delegates.

The final delegate allocation for Colorado: 41 for Sanders, 25 for Clinton.

Overall, Clinton has 1,758 delegates and superdelegates to Sanders' 1,076. A Democratic candidate needs 2,383 delegates to wrap up the nomination.

Earlier Saturday, Pope Francis said his brief encounter with Sanders at the Vatican was a sign of good manners, “nothing more,” and hardly evidence of interfering in U.S. politics.

Sanders called it a “real honor” to meet “one of the extraordinary figures” in the world, a kindred spirit on economic inequality, which is a main Sanders' campaign theme.

Francis was on his way to Greece to highlight the plight of refugees and Sanders was wrapping up his trip to Rome when they met in the lobby of the pope's residence in the Vatican gardens.
