Four states held contests to choose presidential nominees Tuesday, with voters in Michigan, Mississippi, Idaho and Hawaii casting votes.
Donald Trump and Hillary Clinton scored two early wins in Mississippi. But Bernie Sanders narrowly took the big prize by winning Michigan in a late night nail-biter as Trump handily won the state's GOP primary. Late in the evening, Ted Cruz won the Idaho Republican primary and Trump won the Hawaii GOP caucus when the returns came in overnight.

Sanders Says Campaign Has "Come-From-Behind Momentum"
Bernie Sanders, who addressed reporters well before the results of the Democratic primary in Michigan were known, released a paper statement late Tuesday declaring victory and "come-from-behind momentum."
"I am grateful to the people of Michigan for defying the pundits and pollsters and giving us their support. This is a critically important night. We came from 30 points down in Michigan and we're seeing the same kind of come-from-behind momentum all across America."
"Not only is Michigan the gateway to the rest of the industrial Midwest, the results there show that we are a national campaign. We already have won in the Midwest, New England and the Great Plains and as more people get to know more about who we are and what our views are we're going to do very well."

Idaho GOP Primary Too Early To Call
At 11 p.m. ET, NBC News projects the Democratic primary in Michigan is too early to call.
Sanders Takes the Stage Briefly
Bernie Sanders took the stage nearly two hours after Michigan polls closed but the race is still too close to call. Should Sanders win, it would be a huge coup for his campaign as polls indicated Clinton would win the state.
Sanders said that even if he doesn't win, the race would be close enough for the delegates to be split between himself and Clinton.
"What tonight means is that the Bernie Sanders campaign … is strong in eevry party of the country and we firmly believe our strongest areas are yet to happen," Sanders said during a brief election-night appearance.
Kasich Predicts a 'Whole New Ballgame' After Ohio Primary
Ohio Gov. John Kasich said Republican voters have begun rewarding his positive campaign and predicted "a whole new ballgame" after next week's primary in his home state.
"I landed in Cleveland today and I almost got down on my hands and knees to kiss the ground to be back in Ohio," Kasich said Tuesday at a primary night rally in Columbus, Ohio.
Kasich can capture second place behind Donald Trump in Michigan. He is locked in a tight battle with Ted Cruz and both Republicans are well ahead of fourth-place Marco Rubio.
"I think people are beginning to reward a positive campaign," Kasich told supporters.
On the campaign trail, the Ohio governor has attempted to remain above the fray, passing on the opportunities to deliver the kinds of jabs and insults that have characterized the Republican primary.
Though has had impressive showings in some of the primary states, he has yet to win any of the GOP contests. That, he says, will change when Ohioans go to the polls next week.
"We are going to win the state of Ohio and it will be a whole new ballgame," Kasich said.
Trump: 'I hope Republicans Embrace It'
After winning Michigan and Mississippi, Donald Trump said the "single biggest" story in politics today is the record turnout in Republican primaries.
"We'll take many many people away from the Democrats," he said.
In what seems like an effort to soften talk about a split within the Republican Party as Trump moves closer to the nomination, he said "I hope Republicans embrace" his candidacy and his supporters.
Still reeling from the anti-Trump speech by Mitt Romney, Trump brought props to his event, including Trump Steaks, Trump Wine, Trump Water and Trump Magazine, all items that Romney criticized during his speech.
Getting back to his performance, he said, "There's only one person who did well tonight: Donald Trump," Trump said about himself, adding that he insists that he's going to do "really well" in Florida and Ohio.
Clinton Asks for Support During 'Busy Week' in Ohio
Hillary Clinton said it will be a "busy week" in Ohio ahead of next week's primary in the Buckeye State and slammed her GOP rivals for running campaigns centered on insults Tuesday night.
"Running for president shouldn't be about delivering insults, it should be about delivering results," Clinton said during a primary night rally in Cleveland, Ohio.
"Every time you think they can't get any uglier they find a way," Clinton said of her GOP rivals.
Clinton easily won the Democratic primary in Mississippi and is in a too-close-to call race against Sanders in Michigan. She made no mention of either result in her speech, though.
"This has been so far a campaign focused on the issue, and I'm proud of the campaign that Sen. Sanders and I are running," Clinton said.
Delegate rich Ohio holds its primary next Tuesday, and tonight's victor in Michigan will have momentum heading into the next critical primary test.
Sanders hammered Clinton on her support for trade deals that exit polls showed Michigan voters overwhelmingly opposed. Clinton accussed Sanders of opposing the auto bailout credited with helping to save the American auto industry.
Both issues will also play large roles in the Ohio primary.
Michigan Exit Poll Results: How Trump Won
NBC News projects a key win for Donald Trump tonight in Michigan, with a strong showing from both Ted Cruz and John Kasich in the Rust Belt state.
As with earlier primaries, Trump did particularly well in Michigan among voters who are looking for a candidate who "tells it like it is" as well as with those who think the next president should be someone from outside the political establishment. Trump also does well with voters looking for a candidate who can bring needed change in November.
Trump captured 44 percent of the vote among those with some college or less education. College graduates were split among three candidates: Trump, Kasich and Cruz.

Mississippi Exit Poll Results: Inside Trump's Win
Donald Trump won the Mississippi Republican primary Tuesday, performing particularly well with voters who are angry with the federal government and those who think the next president should be a political outsider. Trump won about half of the vote among those with annual family incomes under $50,000, according to the NBC News Exit Poll. Trump also did well with voters in Mississippi who are either somewhat conservative or who are moderate or liberal.
Cruz, who NBC News projects will finish second, beat Trump among voters who are very conservative. Cruz also did particularly well with voters who are looking for a candidate who shares their values. And Cruz won 44 percent of voters who made up their minds within the last week.
Rubio Rails Against Clinton in Primary Speech
Marco Rubio spoke to supporters on Tuesday night after results came in from the Mississippi contest, where he trailed far behind winner Donald Trump. But instead of going after the Republican frontrunner as he's done in recent weeks, the Florida senator launched attacks at Hillary Clinton and President Obama.
"As you can see, we have a lot of work to do, because President Obama has done a lot of damage to America," Rubio said. "We can't embrace a better future if Hillary Clinton is elected president of the United States -- she would follow Obama's agenda."
Clinton was the projected winner in the Mississippi Democratic primary when the polls closed at 8 p.m.
Rubio said Clinton sees him as the biggest threat because "she attacks me more than any other Republican."
Looking forward to the Florida contests next Tuesday, where Rubio said he believes the winner there will be the GOP nominee, he said to supporters, "I need your help."
"you believed in me once, I need you to believe in me again," Rubio said.

Clinton captured 89 percent of the vote among blacks, 87 percent among those age 45 and older and 80 percent among women. She also scored exceptionally well among those who attend religious services at least weekly (85 percent) and those with a high school education or less (90 percent).
And unlike previous contests, in Mississippi, Clinton surpassed Sanders with three key groups—men, whites and voters under age 45. She won 74 percent of the votes from men, 64 percent from those under age 45 and 54 percent from whites.
Cruz Likens Trump Loyalty Oath to Pledging to a King
KANNAPOLIS, N.C. — Ted Cruz equated Donald Trump's loyalty pledge to subjects declaring their devotion to a king on Tuesday.
"The idea that a candidate running for office would want people to pledge loyalty to him like subjects to a king," Cruz began telling reporters. "Well, we've had seven years of a president who thinks he's an emperor."
Cruz continued: "I raise my hand and I give an oath to you, to the people. That's who's working for whom."
