AP - Bernie Sanders says in a statement after his wins in the Idaho and Utah Democratic presidential caucuses that "tremendous voter turnouts" gave his campaign two victories "with extremely large margins."
The Vermont senator says the support in Tuesday's races "give me confidence that we will continue to win major victories in the coming contests."
Sanders pointed to the participation of young people and working-class people, saying it was "exactly what the political revolution is all about."
Hillary Clinton won Arizona's primary against Sanders earlier on Tuesday, and she'll end the night still leading Sanders in the race for the Democratic Party's nomination by more than 300 pledged delegates.
AP - Ted Cruz has won Utah's Republican presidential caucus, and is on pace to take all of the state's delegates by finishing with more than 50 percent of the vote.
Ohio Gov. John Kasich was running second, with GOP front-runner Donald Trump in third.
Cruz's win follows endorsements in the last week from Utah. Gov. Gary Herbert and Mitt Romney, the GOP's last presidential nominee who holds clout among the state's predominantly Mormon voters.
Romney and Herbert backed the Texas senator in an effort to derail Trump's path to victory.
DPA - Senator Bernie Sanders wins the Democratic Party's caucus state of Utah, media reports say.
Sanders beat out Clinton, the overall front-runner in the race for the Democratic party's presidential nominee, according to the Huffington Post and CNN.
Utah awards 11 of its 33 delegates to the Democratic winner, with the remainder distributed proportionately among its four congressional districts.
Hillary Clinton is welcoming her victory in Arizona's presidential primary, pointing to the attacks in Belgium as a sign of "how high the stakes are" in the 2016 election.
Clinton says at a rally in Seattle that the nation needs a commander in chief who is "strong, smart and above all steady" in taking on these types of threats.
In a nod to Republican front-runner Donald Trump, the former secretary of state says the last thing the U.S. needs "are leaders who incite more fear."
She says "in the face of terror, America doesn't panic, we don't build walls or turn our backs on our allies."
Clinton says what Trump and his Republican rival Ted Cruz are suggesting is "not only wrong, it's dangerous." She says it is "time for America to lead, not cower."
Bernie Sanders is brushing off a loss in Arizona, telling thousands of supporters in California that his campaign has won 10 primaries and caucuses and "unless I am mistaken we are going to win a couple more tonight."
Sanders was hoping for victories in caucuses in Idaho and Utah on Tuesday night. Speaking at a rally in San Diego, the Vermont senator says there are "record-breaking turnouts" in the three states.
Sanders trails Democratic front-runner Hillary Clinton, but he says his campaign is generating energy and enthusiasm.
Hillary Clinton has padded her delegate lead after a win in the Arizona Democratic presidential primary.
With 75 delegates at stake, Arizona is the biggest prize of the night in the Democratic race.
Clinton stands to gain more than half of those delegates — at least 40, compared to at least 16 for rival Bernie Sanders.
That means she will add to her delegate lead of more than 300. She now has 1,203 to Sanders' 860.
When including superdelegates, or party officials who can back any candidate, Clinton's overall lead is even wider — 1,670 to Sanders' 886. It takes 2,383 to win.
Also voting this evening are Idaho and Utah, with a combined 56 delegates at stake.
Donald Trump is stretching his lead in the race for convention delegates by winning the Arizona primary.
Trump won all 58 delegates in Arizona, giving him a little less than half the delegates allocated so far. That's still short of the majority needed to clinch the nomination before the party's national convention this summer.
However, Trump has a path to the nomination if he continues to win states that award all or most of their delegates to the winner.
Donald Trump and Hillary Clinton were the big winners of the Arizona primary election, according to incoming figures reported by MSNBC.
In the Republican race, Trump garnered 45 percent of the vote, Sen. Ted Cruz 20 percent and Gov. John Kasich 11 percent.
In the Democratic poll, Clinton received 62 percent of the vote, while Sen. Bernie Sanders got 36 percent.
The Republican race in Arizona is a winner-take-all contest, while the Democratic poll follows the lines of proportional representation.
Donald Trump apparently has no regrets about making a threat against rival Ted Cruz.
The GOP front-runner on Tuesday night tweeted that the Texas senator needed to "be careful" or he would "spill the beans on your wife."
Trump quickly deleted the tweet, but then reposted an edited version a few minutes later.
The change? This time, he called Cruz by the dismissive nickname he uses often: "Lyin' Ted."
Trump appears to be upset about an ad in Utah that uses a photo of his wife, Melania, from a photo shoot that ran in GQ magazine more than a decade ago.
The ad wasn't placed by Cruz's campaign, but rather an outside group that's opposed to Trump's candidacy.
Cruz shot back with a tweet of his own, saying in part, "Donald, if you try to attack Heidi, you're more of a coward than I thought."
Trump's campaign didn't immediately return messages seeking comment about the billionaire businessman's tweet.
Utah is seeing a frenzy of activity surrounding its presidential caucuses as voters are experiencing long lines, and the Democratic Party's website crashed due to high traffic.
Lines have been several blocks long at some Republican caucus sites. And the Democratic site crashed about an hour before the start of the party's caucuses.
Former presidential candidate Mitt Romney isn't among those waiting in line to take part. He is out of town and voted absentee.
The Arizona presidential primary is drawing long lines as people wait two hours in some cases to cast a ballot.
Police have been called to help with traffic control in some places, while one polling place ran out of ballots. Some voters wore wide-brimmed hats or carried umbrellas for shade. Others sat in lawn chairs they brought from home.
Dozens of people were lined up before voting started at 6 a.m. at a central Phoenix polling place, and hundreds were in line there by mid-afternoon.
