WASHINGTON (AP) — The Latest on 2016 presidential sweepstakes following primaries and caucuses Tuesday in Michigan, Mississippi, Idaho and Hawaii:

10:40 p.m.

Hillary Clinton is accusing rival Bernie Sanders of focusing his economic attacks on the past two Democratic presidents — rather than former Republican President George W. Bush.

Clinton said at Wednesday's Democratic debate that she wishes Sanders would join her "in criticizing George W. Bush who I think wrecked the economy."

Her attack is part of an effort to drive a wedge between Sanders, long a self-identified independent, and Democratic primary voters.

Sanders is shooting back, saying he frequently voted against Bush's economic proposals as a senator from Vermont.

"I gather Secretary Clinton hasn't listened to too many of my speeches or followed my work in the Congress," he says.

Hillary Clinton and Bernie Sanders agree on reducing student debt loads. But he says he had the idea first.

Calling current interest rates for student loans "outrageous," Clinton said Wednesday night in a Democratic debate that she has a plan to lower interest rates and limit how long people must repay loans.

Sanders quickly shot back that Clinton was "absolutely right," adding that he thought he said it "many months before she did."

"Thanks for copying a very good idea," he said.

Hillary Clinton is taking a swipe at Bernie Sanders' spending plans.

The Democratic front-runner implied at Wednesday's debate that Sanders' proposals to provide free tuition at public colleges and universities and a universal single-payer health care plan would cost too much.

Clinton said when people ask him questions about how he would pay for his plans, it's "hard to get answers." To that, Clinton said: "My dad used to say, 'If it sounds too good to be true, it probably is.'"

Bernie Sanders is defending his proposal for free tuition at public colleges and universities -- even for the children of wealthy people like Donald Trump and Hillary Clinton.

He said at Wednesday's Democratic debate that he wants young people to know that if they work and study hard, they can continue their studies without being burdened by heavy college debts.

He said he "doubts" that well-off families would choose public universities over private ones, where under his plan they'd still pay tuition.

And he added that his proposal to raise taxes on the wealthy balances his plan to allow their kids attend public schools for free.

10:10 p.m.

Hillary Clinton is defending her role in the deadly 2012 attack on the American mission in Benghazi, Libya.

She said at Wednesday's debate that her shifting explanations for the crisis in the early hours were because of changing dynamics and new information. Clinton also said the investigation has been politicized by Republicans seeking to score points against her campaign.

"This was fog of war," she said, saying that she regrets the lives lost in the crisis.

She added: "I wish there could be an easy answer at the time but we learned a lot."

___

10:05 p.m.

Bernie Sanders is repeating his calls for Hillary Clinton to release the transcripts of her lucrative private speeches to Wall Street firm Goldman Sachs.

He joked at Wednesday's Democratic presidential debate that if her speeches were so great, she should want to "share it with the American people."

He notes that Wall Street recently donated $15 million to the super PAC supporting Clinton's campaign.

Clinton said she has a long public record and she went to Wall Street before the Great Recession and "basically called them out."

She said she has the "toughest, most comprehensive plan to go after Wall Street."

___

10:00 p.m.

Hillary Clinton admits that she is not a "natural politician," but says she tries to do the "best I can."

During a Democratic debate in Miami Wednesday, Clinton was asked about polling that shows many voters think she is not trustworthy.

"Obviously it's painful for me to hear that," Clinton said, adding that she said she takes "responsibility."

Clinton said she has committed herself to helping people and tries to show people that they can count on her. She said she was not a "natural politician," like her husband or President Barack Obama, but she hoped people can "see that I'm fighting for them."

9:50 p.m.

Hillary Clinton got some laughs by saying Donald Trump wants to build "a beautiful, tall wall" that will "magically" be paid for by the Mexican government.

Her comments came in response to a question at Wednesday's Democratic presidential debate in Miami on whether her vote as a New York senator to build a wall on the Southern border differs from Trump's plan, which she has called ridiculous.

Clinton says responsible legislators chose to improve border security with more agents and some fencing when needed, and as a result the country has lower rates of illegal immigration.

___

9:40 p.m.

Bernie Sanders says rival Hillary Clinton is misrepresenting her vote for a federal bailout of the auto industry.

The 2008 vote, he said Wednesday, was part of a larger legislative package that benefited big Wall Street banks.

At the time, Clinton represented New York in the Senate. Sanders told a Miami audience attending the Democratic debate that Clinton backed the bill then because it helped a home-state industry.

"Then you go to Detroit and suddenly this legislation helps autoworkers," he says.

Clinton said it was a "hard vote" and if everyone joined Sanders then the industry would have failed.

___

9:35 p.m.

Hillary Clinton and Bernie Sanders are continuing to fight over the details of immigration policy.

Clinton vowed at Wednesday's Democratic president debate not to deport children and immigrants without a criminal record. She said she will prioritize deporting violent criminals, terrorists and those who threaten the nation's safety.

Sanders said Clinton supported turning back children flowing into the country from Honduras and said he wouldn't deport children or immigrants without criminal records.

Clinton was pressed on whether she would follow President Barack Obama's approach, which moderator Jorge Ramos said would be tantamount to becoming "the next deporter-in-chief."

Clinton says she doesn't have the same policies of the "current administration" and would move to "stop the raids" and "stop the roundups."

9:25 p.m.

Hillary Clinton and Bernie Sanders are sparring over their immigration records during a Democratic debate in Miami.

In a lengthy back and forth in the latest debate Wednesday night, the Democratic presidential candidates both affirmed their commitment to immigration reform and sought to poke holes in the other's voting history.

Clinton says she has long been "committed to comprehensive immigration reform" and stressed that Sanders had voted against a 2007 immigration bill.

"Just think, imagine where we would be today if we had achieved comprehensive immigration reform nine years ago," Clinton said.

Sanders said he had concerns about the treatment of guest workers and noted he supported a 2013 immigration bill. He argued that Clinton had sought to block driver's licenses for undocumented immigrants in 2008. "She said don't do it and New York state still does not do it," he said.

9:20 p.m.

Hillary Clinton is calling Republican presidential candidate Donald Trump "un-American."

She says Trump trafficks in "prejudice and paranoia" and says voters can draw their own conclusions about him. She tries to turn Trump's campaign slogan on its head, saying, "You don't make America great again by getting rid of everything that made America great."

Bernie Sanders says voters will "never elect" someone like Trump, pointing out that he has insulted many kinds of people, including African Americans, women and Muslims. He is reminding voters that Trump was part of the "birther" movement to tag President Barack Obama as not American.

___

9:15 p.m.

Hillary Clinton is dismissing questions about whether she'd drop out of the presidential race should her use of a private server while secretary of state result in a federal indictment.

"Oh for goodness and it's not going to happen," she says, responding to a question from moderator Jorge Ramos. "I'm not even answering that question."

Clinton insists she broke no rules by running her State Department email account from a private server located in her New York home, though she now calls the decision "a mistake." The messages were classified by government agencies years after she sent them, she says.

"I did not send or receive any emails marked classified at the time," says Clinton. "What you're talking about retroactive classification."

___

9:10 p.m.

Hillary Clinton says the primary campaign is a "marathon" and she will "work hard for every single vote" despite her loss to Bernie Sanders in Michigan.

Clinton was asked about her surprising loss to Sanders in Michigan's primary. She notes that she won in Mississippi and ended the night with more delegates.

Sanders is trailing Clinton among pledged delegates but he says in the "coming weeks and months" his campaign is going to do "extremely well." He says he can convince superdelegates that he's the strongest candidate to defeat Republican businessman Donald Trump.

___

9:08 p.m.

Hillary Clinton began her pitch to a Miami audience by reiterating her call to "knock down barriers."

In her opening remarks at the latest Democratic presidential debate Wednesday, Clinton said she is committed to raising incomes and creating good jobs. She also urged for improving education so that all children can benefit.

Her rival Bernie Sanders repeated his rally call to end "establishment politics and establishment economics," saying that the economy is "rigged."

He also vowed to create jobs and better wages if he is elected president.

Republican presidential front-runner Donald Trump is escalating his attacks against rival John Kasich as the Ohio governor appears to be making gains.

Trump tells a crowd of thousands in Fayetteville, North Carolina that Kasich is an "absentee governor."

He says he expects to "do great, great, great in Ohio," which will be voting next week.

The attack comes as a new Fox Poll shows Kasich pulling ahead of Trump in Ohio.

Trump is also predicting a strong showing in Florida, home of rival Marco Rubio.

"It's going to be amazing," he says, adding: "I think we're going to have a fantastic week."

Trump was speaking to a crowd of thousands at a local hockey arena at a rally that was repeatedly interrupted by protests.

The latest Democratic presidential debate is set to begin in Miami with host, Spanish-language network Univision set to quiz the candidates.

Hillary Clinton and Bernie Sanders will face off Wednesday for the second time in a week, this time since Sanders' upset victory in the Michigan primary Tuesday night.

The two are now in a race to win the crucial upcoming contests in Florida and Ohio, Sanders' campaign saying the Vermont senator still stands a chance to win the nomination, despite Clinton's significant delegate lead.

8:50 p.m.

One of the most vocal groups opposing Donald Trump is pelting Ohioans with $1 million in commercials over the next five days.

They're paid for by Our Principles PAC, a collection of wealthy donors and GOP strategists who want to keep the controversial New York businessman from becoming the party's presidential nominee.

The new ads attack Trump as a jobs outsourcer. Indeed, as Trump has acknowledged, some of his products been made in countries such as China.

The group also is spending $2 million in Florida, according to advertising tracker Kantar Media's CMAG. Florida, where Trump rival Marco Rubio is a senator, and Ohio, where candidate John Kasich is governor, both weigh in Tuesday on the Republican primary.

Our Principles is supplementing its air war with voter calls and mail.

6:55 p.m.

Marco Rubio says he's "not entirely proud" of his deeply personal attacks on Donald Trump and would have handled his critiques of the GOP front-runner differently if he could do it all over again.

The Florida senator, whose standing has fallen since he launched the Trump attacks, says his own children were "embarrassed" by his actions.

Rubio garnered significant attention for criticizing Trump's tan, his hair and his hand size. But the attacks did little to slow the billionaire's march toward the nomination or boost Rubio's own standing.

In a town hall with MSNBC, Rubio says he knows the attacks are "not what we want from our next president."

4:45 p.m.

NASCAR chairman and chief executive Brian France says his personal endorsement of Donald Trump for president was nothing more than a "routine endorsement."

But he's been dealing with the fallout ever since.

France's decision to personally back the front-runner for the Republican nomination is roiling a sport his family built from the ground up. It's threatening a decade of work to broaden NASCAR's appeal among minorities, upset one of the most powerful teams in the sport and risked a break with the corporate sponsors that are its financial lifeblood.

France says of the reaction that he is "very surprised" that his efforts to foster diversity are being "called into question."

He says he's had conversations with sponsors since the endorsement, which came as NASCAR is seeking a new main sponsor for its top series.

___

4:10 p.m.

Ohio Gov. John Kasich says his turnout in the Michigan primary is indication that voters are "hearing my message."

Speaking in Palatine, Illinois Wednesday, Kasich said that his campaign "went from obliterated, where everybody counted me out to basically tied with Ted Cruz."

He said he expects to win the winner-take-all primary in his home state next week and pick up some delegates in the Illinois primary.

Kasich also said he has no idea what will be discussed at a meeting scheduled for Thursday with former GOP rival Jeb Bush, but that he would like the former Florida governor's endorsement.
