WASHINGTON (AP) — The Latest on the 2016 presidential campaign, with contests in Maine and Puerto Rico on Sunday and a Democratic debate in Flint, Michigan (all times Eastern Standard Time)

9:50 p.m.

Hillary Clinton says she has a lot of conditions that must be met when it comes to fracking. Bernie Sanders says he outright opposes it.

During a Democratic debate in Flint, Michigan Sunday, both Democrats were asked if they supported fracking, a method of oil and gas drilling that environmentalists have opposed.

Clinton said she would not support fracking if there was local opposition, if methane was released or water contaminated or unless those fracking explain what chemicals they are using.

“So by the time we get through all of my conditions, I do not think there will be many places in America where fracking will continue to take place,” said Clinton.

Sanders was brief: “My answer is a lot shorter. No, I do not support fracking.”

9:44 p.m.

Hillary Clinton is defending against a suggestion that her plan to fix infrastructure is not big enough.

She said in Sunday night’s Democratic presidential debate that her $250-plus billion proposal is a “very good way to begin” upgrading water systems and pipelines. Her opponent, Bernie Sanders, is calling for $1 trillion in infrastructure spending.

A moderator questioned Sanders about how he could deliver that much since President Barack Obama got a $300 billion highway bill through Congress.

Sanders says he would stop American corporations from avoiding taxes by “stashing profits” in the Cayman Islands and Bermuda. He says spending $1 trillion over 5 years would create 13 million jobs.

9:30 p.m.

Hillary Clinton says people often “blamed and scapegoated teachers” for education shortfalls, but that poor funding is more to blame for under-performing schools than the unions.

Clinton was asked at Sunday’s Democratic presidential debate whether unions protect bad teachers. The former secretary of state has been endorsed by both the National Education Association and the American Federation of Teachers.

Clinton says she has told her friends at the top of both unions to “take a look at this” and if there is “anything that could be changed, I want them to look at” potential improvements.”

9:10 p.m.

Hillary Clinton and Bernie Sanders are criticizing former President Bill Clinton’s 1994 crime bill.

The Democratic presidential candidates were asked about the legislation during a debate in Flint, Michigan Sunday night. Critics argue that the bill has ushered in an era of mass incarceration.

Clinton noted that Sanders had voted for the bill and said she agreed with recent comments from former President Bill Clinton that “it solved some problems but it created other problems.”

Sanders said the bill had both pros and cons, but that his comments raising concerns at the time reflected that he “was a congressman who was torn.”

9:00 p.m.

Hillary Clinton and Bernie Sanders are tussling over whether gun manufacturers should be legal liable when their weapons are used in crimes.

Clinton said in Sunday’s Democratic presidential debate that giving immunity to gun makers and sellers “was a terrible mistake” and notes that she and Sanders were on opposing sides of the debate.

Sanders has said his support for the 2005 law was in part an effort to protect small gun shops in his home state of Vermont. He says during the debate that Clinton’s approach could amount to “ending gun manufacturing in America.”

Clinton is bringing up the Sandy Hook massacre and tells Sanders, “you talk about corporate greed. The gun manufacturers sell guns to make as much money as they can.”

8:55 p.m.

Michigan Gov. Rick Snyder is responding to calls for his resignation by Democratic presidential candidates Hillary Clinton and Bernie Sanders over the contaminated water crisis in Flint, Michigan.

The Republican governor took to social media Sunday night.

He says “political candidates” will be leaving Flint and Michigan in a few days after the state’s primary, but he is “committed to the people of Flint.” Snyder says “I will fix this crisis and help Michigan forward.”

Clinton called for Snyder’s resignation for the first time during Sunday’s debate, saying he should either resign or be recalled from office. Sanders has previously demanded that Snyder step down.

Snyder has apologized for the disaster but has said there were failures at the state, federal and local levels.

8:40 p.m.

Hillary Clinton and Bernie Sanders are at odds over his past opposition to the federal Export-Import Bank, which makes and guarantees loans to help foreign customers buy U.S. goods.

In Sunday’s Democratic debate, Clinton criticized Sanders, saying the U.S. is in a “race for exports” and that without the bank, “more jobs would be lost here at home.”

Sanders counters 75 percent of the money goes to profitable corporations such that have outsourced jobs overseas. He was the only Democrat to oppose the bank, but he says “Democrats are not always right” and “have often supported corporate welfare.”

Clinton says Boeing deserves assistance from the government to keep pace with Airbus, because the U.S. is not as “aggressive” as other countries.

Asked if he was agreeing with Republican Sen. Ted Cruz, Sanders says “Democrats are not always right” and Democrats have supported “corporate welfare” in the past. Sanders is the nation’s longest-serving independent member of Congress and has caucused with Democrats in the Senate.

8:30 p.m.

Hillary Clinton is arguing that Bernie Sanders opposed the bailout of the auto industry.

During a Democratic debate in Flint Sunday night, Clinton said she voted to save the auto industry, while Sanders, she said, “voted against the money” that saved the auto industry.

Sanders said that Clinton was talking about the Wall Street bailout package, through which “some of your friends destroyed this economy.” Clinton tried to rebuttal but Sanders uncharacteristically snapped back: “Excuse me, I’m talking.”

Clinton replied: “If you’re going to talk, tell the whole story.”

Clinton later called the vote a hard but necessary choice, saying that “If everybody had voted the way he did, I believe the auto industry would have collapsed taking 4 million jobs with it.”

8:25 p.m.

Bernie Sanders says he’s glad that Hillary Clinton has “discovered religion” on trade but he says it’s too late.

At the CNN Democratic debate in Flint, Michigan Sunday, Sanders accused Clinton of supporting “disastrous trade agreements” such as the North American Free Trade Agreement and normalizing trade relations with China that he says have led to job losses.

Sanders spoke after Clinton discussed a number of ways to help manufacturing jobs.

Clinton says there needs to be both “carrots and sticks” so that manufacturers make investments in the U.S.

She says the country needs a comprehensive plan for manufacturing and improve roads and bridges.

8:15 p.m.

Democrats Hillary Clinton and Bernie Sanders say people at the Environmental Protection Agency should their lose jobs over the Flint water crisis.

Asked whether she would fire the head of the EPA over the lead-tainted water, Clinton said Sunday night during a Democratic debate in Flint that she would launch an investigation “and determine who knew what, when, and yes people should be fired.”

To the same question, Sanders said a “President Sanders would fire anybody who knew what was happening and did not act appropriately.”

8:10 p.m.

Hillary Clinton says as president, she would assure Flint residents that their water has been double- and triple-checked before telling them it is OK to use it again.

In the Democratic debate in the Michigan city, she is applauding President Barack Obama’s for pushing for the resignation of a regional administrator because of Flint’s water crisis and says he was right to expand Medicaid to help people there. She also says health and education interventions must be done to help Flint children with elevated lead levels.

Bernie Sanders says if the state government refuses to act, he as president would ensure that federal government acts immediately. He says something also must be done about Flint’s high water rates.

8:07 p.m.

Hillary Clinton is echoing calls by her rival Bernie Sanders for the resignation of Republican Gov. Rick Snyder of Michigan, saying he should either resign or be recalled from office in the aftermath of Flint’s water crisis.

Clinton says in her opening statement in the Democratic debate that “it is raining lead in Flint” and more needs to be done to help the residents of Flint deal with the aftermaths of contaminated drinking water.

Sanders notes in his opening statement that he had called on Snyder to resign for his “dereliction” of duty. He says what is happening in Flint is happening throughout the country to a lesser degree.

Clinton says: “Amen to that.”

8:05 p.m.

Bernie Sanders’ win in Maine will give him more delegates than Hillary Clinton for the night. But it won’t have much impact on Clinton’s substantial lead overall.

With 25 Maine delegates at stake, Sanders is assured of winning at least 14 while Clinton stands to gain at least six.

He can now lay claim to winning eight of the 19 states that voted in primaries or caucuses to date, having prevailed in Maine, Kansas and Nebraska over the weekend.

But Sanders is making little headway in delegates after Clinton’s large margin of victory in Louisiana on Saturday.

For the weekend, out of 134 delegates at stake, Sanders will win at least 66 and Clinton at least 63. Five delegates remain to be allocated in Maine.

8:05 p.m.

Bernie Sanders has won the Democratic presidential caucuses in Maine, beating rival Hillary Clinton for his eighth win in the nomination process.

Prior to the contest in Maine, Clinton had at least 1,123 delegates to Sanders’ 484, including superdelegates — members of Congress, governors and party officials who can support the candidate of their choice.

It takes 2,383 delegates to win the Democratic nomination.

Texas Sen. Ted Cruz won in Maine’s Republican caucuses on Saturday.

8:00 p.m.

At the start of the Democratic debate in Flint, Michigan, Hillary Clinton and Bernie Sanders are bowing their heads with the audience in a moment of silence to honor former first lady Nancy Reagan, who died Sunday.

The wife of former President Ronald Reagan was 94.

7:55 p.m.

The latest Democratic presidential debate is about to begin in Flint, Michigan, where a contaminated water crisis has become a major focal point of the campaign.

Hillary Clinton and Bernie Sanders will face off in the CNN debate Sunday as Democratic caucusing is wrapping up in Maine, where 25 delegates are up for grabs.

Clinton has added to her overall delegate lead after winning most of the delegates at stake in Saturday’s contests.

Out of 109 delegates, she won 57 while Bernie Sanders picked up 52.

Sanders won the Kansas and Nebraska caucuses, but his gains were overcome by Clinton’s large margin of victory in Louisiana.

6:55 p.m.

John Kasich believes he can convince some of Donald Trump’s supporters to back him instead of the billionaire because he has better answers on how to fix the nation’s problems.

Kasich tells The Associated Press that he doesn’t think it will be very hard to bring Trump voters his way as his message becomes more familiar. On the trail, Kasich often says he understands peoples’ economic anxieties because he grew up in a scrappy blue collar town in Pennsylvania.

He says, “If they can hear me, and what I’ve done, that’s the ticket. I believe that if I can sit with some Trump people - I won’t get them all - if I can sit with them they’re gonna understand that I’m one of them.”

6:50 p.m.

Ohio Gov. John Kasich is lagging far behind his rivals in the delegates needed to clench the nomination, with just 35 compared to Trump’s 382.

But he remains confident in his ability to win his home state of Ohio on March 15 and go on to win the nomination, even if he has to wrest it from Trump at a contested convention this summer.

“Don’t doubt my tenacity in this,” he says.

In the recent GOP debate in Detroit, Kasich said he would support Trump if the businessman becomes the nominee, although he noted Trump sometimes says things that would make supporting him hard.

Kasich notes that he took on Trump last year over his position to deport everyone living in the country illegally. Kasich does not support mass deportation.

“I see these things and they bother me,” he says of Trump.

6:45 p.m.

Workers advocating for a higher minimum wage are demonstrating outside the Democratic debate venue in Flint, Michigan.

Roughly 100 people from the Fight for 15 — fast food workers seeking a $15 per hour minimum wage — gathered Sunday near the Flint Cultural Center, chanting: “What do we want? Fifteen! When do we want it? Now!”

Kendall Fells, the national organizing director for the group, said the activists were from the Detroit and Flint chapters of the organization. The group has protested at all the Democratic and Republican debates calling for the right to form a union, boost the minimum wage to fifteen dollars-an-hour and achieve racial equality.

Tyrone Stitt, 43, of Flint, said he has been working at Taco Bell for 18 years and makes $8.50 an hour, which he says is not “enough to survive.”

6:30 p.m.

Republican presidential front-runner Donald Trump says that as president, he would push to change laws that prohibit waterboarding and other, more extreme forms of torture.

He argues that banning it puts the U.S. at a strategic disadvantage against Islamic State militants.

Over the past week, in a series of interviews and events, Trump has articulated a loose, but expansive set of principles that, if enacted, would mark a fundamental shift in U.S. foreign policy from the limits put in place by the administration of Democratic President Barack Obama.

In addition to arguing in favor of reinstating waterboarding, a technique that mimics the sensation of drowning, and “much more than that,” Trump has advocated the killing of suspected terrorists’ wives and children.

5:45 p.m.

Marco Rubio will collect all 23 of Puerto Rico’s delegates after posting a huge win in the U.S. territory. But he still lags far behind rivals Donald Trump and Ted Cruz.

Like many states, Puerto Rico awards all the GOP delegates to a candidate who gets more than 50 percent of the vote. Rubio was well above that threshold in the Sunday contest.

Based on updated results, Trump and John Kasich also picked up delegates in Vermont, which held its primary Tuesday.

In the overall race for delegates, Trump has 384 and Cruz has 300. Rubio has 151 delegates and Kasich has 37.

It takes 1,237 delegates to win the Republican nomination for president.

4:55 p.m.

Hillary Clinton has added to her overall delegate lead after winning most of the delegates at stake in Saturday’s contests.

Out of 109 delegates, she won 57 while Bernie Sanders picked up 52.

Sanders won the Kansas and Nebraska caucuses, but his gains were overcome by Clinton’s large margin of victory in Louisiana.

The two candidates are competing in the Maine caucuses on Sunday, where 25 delegates are up for grabs.

Including superdelegates, Clinton now has 1,123 delegates and Sanders has 484. It takes 2,383 delegates to win.

4:05 p.m.

Florida Sen. Marco Rubio has won Puerto Rico’s Republican primary, his second win of the race for the GOP presidential nomination.

It wasn’t clear how many delegates the contest awards him.

The U.S. territory’s three super-delegates have committed to Rubio.

If a candidate gets more than half the votes, he gets all the delegates. If no one gets half, the delegates are divided proportionally.

In addition officials say the votes that some 6,000 inmates cast on Friday won’t be available until Wednesday.

Rubio also won Minnesota.
