Republican and Democratic voters cast their ballots in Tuesday's presidential contests in Arizona and Utah. Democrats also caucused in Idaho and Republicans in American Samoa, a U.S. territory. Arizona was considered the day's biggest prize for both parties. Following the results tonight are Newsweek's Matthew Cooper, Emily Cadei, Taylor Wofford and Michele Gorman.

4:40 am: Well, it took awhile but results are in from all of tonight's contests. Ted Cruz won in Utah as did Bernie Sanders. Only Democrats voted in Idaho today and Sanders won there, too. — Matthew Cooper

12:15 am: Hillary did something tonight I haven't seen before. She made an effort to reach out to Trump supporters even as she denounced him. She tried to explain to her audience why those people at those Trump rallies are so angry. It wasn't the deft touch of Jimmy Carter courting George Wallace voter or Bobby Kennedy crossing racial lines but it was, at least, interesting. — Matthew Cooper

12:05 am: In remarks to supporters in Seattle, Clinton promises to "give back the hope that every American should have that their hard work will get them ahead … that's what we want for America." She brings up the the attacks in Brussels the previous morning, which the former secretary of state suggests reinforces the high stakes in the 2016. "The last thing we need my friends are leaders who incite more fear," Clinton says, dismissing suggestions that the U.S. should build walls and bring back torture. And she doesn't hesitate to name names. "What Donald Trump Ted Cruz and others are suggesting is not only wrong, it's dangerous." — Emily Cadei

11:43 pm: Sanders comes out to speak to a crowd of 9,000 noisy fans in San Diego, who seem pretty pumped despite his big loss in Arizona tonight. The Vermont Senator points out -- very hoarsely, he seems to be close to losing his voice -- that when he began this campaign "we were considered a fringe candidate," but now he's just 5 points behind Clinton in national polls. His campaign has also won ten primaries and caucuses. "And unless I'm very mistaken, we're going to win a couple more tonight!" — Emily Cadei

11:30 pm: CNN just called Arizona for Clinton on the Democratic side, with what looks likely to be a double-digit victory in the state. With about half the vote in, she's up by 25 points. Arizona's delegates are awarded proportionally in the Democratic race, but if Clinton keeps that kind of margin, she'll continue to build on her delegate edge over Sanders. — Emily Cadei

11:28 pm: The Sanders campaign really hoped to win tonight and it's not looking that way. He put more money in the state than any candidate in either party and he spent a lot of time criss-crossing the state not only courting progressives and the large Latino population but also Native Americans. There are plenty of other ripe states for Sanders coming up: Washington this weekend, Wisconsin soon, and California at the end of the process. But after losing five states last week to Clinton, losing the largest of tonight's contests is no help. —Mattew Cooper

11:30 pm: CNN just called Arizona for Clinton on the Democratic side, with what looks likely to be a double-digit victory in the state. With about half the vote in, she's up by 25 points. Arizona's delegates are awarded proportionally in the Democratic race, but if Clinton keeps that kind of margin, she'll continue to build on her delegate edge over Sanders. — Emily Cadei

11:24 pm: CNN is projecting Donald Trump will win the Arizona primary, meaning he will nab all 58 votes in the winner-take-all election. That's a big victory for him, particularly as he's not expected to do very well in Utah. This win keeps his momentum going and helps him continue to rack up delegates, pushing him closer to sewing up the nomination before Republican's convention. — Emily Cadei

11:16 pm: The Associated Press has called Arizona for Donald Trump on the Republican side and Hillary Clinton on the Democratic. The results are not surprising; Trump and Clinton were favored to win there. But it shows just how far apart Republican and Democratic primary voters are on the issue of immigration. Latino voters seem to be coming out in large numbers for Hillary Clinton, who has said she will stop deporting undocumented families, while Trump, who supports building a big, beautiful wall on the U.S.-Mexican border, is winning the support of Republicans in states with large immigrant populations. — Taylor Wofford

11:08 pm.: Looks like Hillary Clinton has opened up a sizable lead over Bernie Sanders in Arizona, with just over 40 percent of voting returns in. That's a blow to Sanders. While he's not favored there, he was still hoping to have a stronger than expected showing in all three Western states voting tonight. And it's likely an indicator of Clinton's strength with Latino voters. — Emily Cadei

10:36 pm: Cruz responds to Trump's crass vulgarity with performative moral outrage. Should play well in Utah.

Pic of your wife not from us. Donald, if you try to attack Heidi, you're more of a coward than I thought. #classless

Fore more information on the candidates' spouses, including Heidi Cruz, read this. — Taylor Wofford

10:35 pm: The attacks in Brussels have dominated the news today and the reactions on the GOP side have been particularly interesting. Trump reiterated his proposed temporary ban on Muslim immigration to the U.S. and briefly extended it saying he wanted to close the borders before walking that back. Meanwhile, Ted Cruz spoke of increased patrols of Muslim neighborhoods but didn't have specifics of who would do the patrols, what would merit a patrol and what they'd be looking for. John Kasich took a temperate we're-not-at-war-with-Islam tone but he did denounce President Obama for not cutting short his Cuba visit to return to the U.S. — Matthew Cooper

10:22 pm: CNN is reporting that one caucus site in Salt Lake City, Utah is handing out provisional ballots because the turnout was so unexpectedly large they ran out of normal ballots. And there have been images circulating of lines winding around the block at polling places in Arizona. Big turnout in Idaho's Democratic caucuses, as wella sign of how much this election is already engaging voters across the country. — Emily Cadei

10:10 pm.: Four states share a border with Mexico—California, Arizona, New Mexico and Texas. Arizona has had the hottest immigration politics. Its immigration control law was adjudicated by the Supreme Court, which left parts of it standing. It's been a great state for Trump. He went there shortly after he announced for President last June. It should be Trump country tonight but we'll see. — Matthew Cooper

10:02 pm: Polls just closed in Arizona. Both the Democratic and Republican primaries are too early to call, per NBC News. Remember, both parties view the Grand Canyon State as the biggest contest of the day. Both Trump and Clinton had double digit leads over their opponents prior to today's voting there, and wins could further enhance their respective leads. — Michele Gorman

9:58 pm: Donald Trump is in top form tonight. Before any results came in, Trump tweeted, then deleted, then re-tweeted a thinly-veiled threat against rival Ted Cruz's wife. Politics! — Taylor Wofford

Lyin' Ted Cruz just used a picture of Melania from a G.Q. shoot in his ad. Be careful, Lyin' Ted, or I will spill the beans on your wife!

— Donald J. Trump (@realDonaldTrump) March 23, 2016

9:41 pm: Ted Cruz and Donald Trump had less moderate reactions to the attacks. Trump called for the borders to be closed. Cruz called for increased surveillance of Muslim neighborhoods, citing the NYPD's surveillance of Muslim neighborhoods in New York post-9/11. That program, later abandoned by the NYPD, didn't produce any leads. — Taylor Wofford

9:14 pm: Earlier in the day, Ohio Governor John Kasich told Fox News that he thinks President Obama should return from his trip to Cuba and Argentina after today's terrorist attack in Brussels, Belgium. Obama and the first family spent three days in Cuba, the first time a sitting U.S. president has visited the island since Calvin Coolidge visited in 1928. — Taylor Wofford
