WASHINGTON (AP) — The Latest on the 2016 presidential campaign, with the focus Sunday on Wisconsin, which holds its primaries Tuesday (all times Eastern Daylight Time):
Texas Sen. Ted Cruz is giving a shout-out to conservative talk radio hosts in Wisconsin who are supporting his campaign.
Cruz says they are "smart and engaged and willing to stand up and speak the truth."
Cruz's rival Donald Trump gave interviews last week with three radio hosts, all of whom oppose his candidacy.
He hung up on one of them, Vicki McKenna, who served as emcee of Cruz's nighttime rally in Eau Claire. Two other radio hosts who last week aired combative interviews with Trump were also hosting rallies for Cruz in Green Bay and in Milwaukee.
Wisconsin's influential conservative talk radio hosts have helped energize the anti-Trump movement in Wisconsin.
Bernie Sanders is disputing the Democratic National Committee's debate rules, saying his and Hillary Clinton's campaign previously agreed to not hold debates on Fridays, Saturdays or holidays.
Sanders spokesman Michael Briggs says Sunday debates were allowed.
The DNC says the campaigns had agreed to debate on weekdays — not holidays or weekends.
Both candidates want to debate before the April 19 presidential primary in New York. But when to debate has become a topic of debate.
Sanders' campaign wants to do it next Sunday in conjunction with NBC, MSNBC and Univision.
They say Clinton's proposal for an April 15 face-off on ABC's "Good Morning America" would been seen by a smaller audience.
Bernie Sanders has hundreds of people on their feet in Madison, Wisconsin, the state's most liberal city.
The Democratic presidential candidate rallied supporters at the Kohl Center on the University of Wisconsin-Madison campus on Sunday evening. Police put the crowd about 4,400 people.
Sanders opened his speech by going after Republican Gov. Scott Walker. He accused Walker and other GOP governors of trying to suppress the vote. Walker signed a law in 2011 requiring Wisconsin voters to show photo ID at the polls. Sanders also took Walker to task for shutting down public employees unions and refusing to expand Medicaid in Wisconsin.
Walker dropped out of the race for the Republican presidential nomination in September. He campaigned Sunday in Wisconsin with a former rival, Texas Sen. Ted Cruz.
For the first time in two days, a Donald Trump rally has been interrupted briefly by protesters.
Trump was about 10 minutes into a speech at a West Allis, Wisconsin, high school when a man stood up to shout his opposition.
"The people of West Allis reject you!" the man yelled before being peacefully escorted out by police.
Trump was later interrupted by a group of young people, holding signs.
"Isn't it fun to be at a trump rally?" the candidate asks, before panning the protesters as "lost" and their demonstration as "sad."
Trump has attracted relatively few protesters during his swing through Wisconsin, a significant departure from the repeat interruptions and outbreaks of violence that marked his rallies in some other states.
Donald Trump opened his latest Wisconsin rally by saluting a newly crowned golf champion.
Trump took the stage at a high school in West Allis on Sunday with a soliloquy about Jim Herman. Trump had just watched on TV as Herman won the Shell Houston Open. Herman now qualifies to play at the Master.
A decade ago, Herman was an assistant professional at a Trump-owned golf club in New Jersey, when he played a round with the celebrity businessman. Herman said Trump told him he was as talented as the golfers with whom the real estate tycoon had previously played.
Herman has said Trump's kind words convinced him to stick with the sport.
Wisconsin Gov. Scott Walker says he's enjoying campaigning in his home state — even though it's for a former rival.
Walker is campaigning alongside Texas Sen. Ted Cruz on Sunday. Walker also plans to be with the senator on Monday and again on Tuesday, when Wisconsin holds its presidential primaries. Forty-two delegates are at stake.
Walker ended his presidential bid in September. He endorsed Cruz last week. Walker spoke briefly with The Associated Press in between shaking hands with voters as he and Cruz worked their way through a restaurant in the central Wisconsin city of Wausau.
Walker is telling voters to back Cruz because he believes a win in Wisconsin could change momentum in the race.
Polls show Cruz leading in Wisconsin but he trails Donald Trump in delegates. Trump was also campaigning around the state on Sunday.
The Democratic National Committee is weighing in on the debate over debates, saying both Hillary Clinton and Bernie Sanders previously agreed that remaining primary face-offs must be held on weekdays — not holidays or weekends.
That rules out Sunday, April 10, proposed by Sanders and NBC News. The DNC is also requesting five to seven days advance notice to give news sponsors time to advertise and build a set for the event.
The two campaigns agreed in February to add four debates to their primary schedules. Two were held in New Hampshire and Flint, Michigan. The campaigns have agreed on a third debate before the New York primary on April 19. But when to hold it is being debated.
"The eight debates we've already had have set records on the strength of our candidates and the visions they've shared to keep America moving forward," said DNC spokesman Luis Miranda. "We look forward to seeing them take the stage."
But both sides are playing political games with scheduling, underscoring the rising tensions between the camps before the New York primary. Clinton said she's participating in a forum with ABC's "Good Morning America" on April 15 — a day Sanders says he's unavailable.
Her campaign also says she'd participate on the evening of April 14 in Brooklyn with local TV station NY1 and the New York Daily News as sponsors. Though Sanders proposed that date several months ago, he's now turning it down. His campaign says they're holding a big rally that evening in New York City.
Sanders's campaign has countered by offering April 10, 11, 12 or 13 — all days the Clinton campaign says they're unavailable.
At this point, the only thing certain about the debate is the location: It will be held in New York City, likely in Brooklyn — the location of Clinton's campaign headquarters and Sanders' childhood home.
Hillary Clinton has made a series of stops at churches in Brooklyn, New York, to "earnestly and humbly" ask for support in the state's Democratic presidential primary on April 19.
At Brown Memorial Baptist Church, Clinton said that contest is an important one "to set the direction for the final determination" of who will be the party's nominee.
Clinton then added, "I know we have to have a Democrat succeed Barack Obama."
That was a dig at her opponent, Brooklyn-born Bernie Sanders. The Vermont senator has identified as an independent for most of his political career.
Lots of Green Bay Packers references at Ted Cruz's campaign rally in that Wisconsin town.
Supporters are chanting the Texas senator's name in much the same way that Packers fans at nearby Lambeau Field yell for players.
A former Packer defensive end, Kabeer Gbaja-Biamila (kah-BEER' BAH'-zhah bee-ah-MEE'-lah), is speaking in support of Cruz at the event — two days before Wisconsin's GOP presidential primary.
Cruz is making a football joke at rival Donald Trump's expense.
Cruz is laughing about imagining Trump dropping back as quarterback and then seeing Gbaja-Biamila coming across the line. Cruz says, "I think Donald's hair would stand on end."
Donald Trump is predicting a "great success" is Wisconsin, despite polls showing him trailing rival Ted Cruz ahead of Tuesday's GOP presidential primary.
"It feels to me like New Hampshire," the billionaire businessman told reporters after sitting down for breakfast at a Milwaukee diner.
Trump led polls in New Hampshire for months ahead of a commanding victory, but says, "A lot of people thought I was going to lose New Hampshire. And we won in a landslide."
Trump held three rallies across Wisconsin on Saturday and pointed to his crowds as a sign of his momentum.
In his words: "I think this has the feel of a victory."
That's' what Donald Trump wants rival John Kasich (KAY'-sihk) to do — quit the Republican presidential race.
Front-runner Trump says the Ohio governor — who's only won his home state among the many nominating contests so far — shouldn't be allowed to keep accumulating delegates if he has no chance.
In Trump's words, "Kasich should not be allowed to run. He's one for 29."
Trump spoke to reporters while grabbing breakfast Sunday at Miss Katie's Diner in Milwaukee. Wisconsin holds its primary on Tuesday.
Trump says Kasich has no shot at getting the required number of delegates needed to win the nomination. The billionaire businessman says this about Kasich: "He's taking my votes."
Trump says he relayed his concerns to Republican National Committee officials at a meeting in Washington this past week.
He says that Kasich can ask to be considered at the party's nominating convention this summer without continuing to run.
GOP Chairman Reince Priebus (ryns PREE'-bus) says party rules mean it's possible for someone not now running for president to become the nominee.
Donald Trump's negatives keep rising among women and other voter groups, and Ted Cruz and John Kasich trail in the delegate count. There's speculation the party could turn at the nominating convention to a "white knight" such as House Speaker Paul Ryan.
Priebus tells "Fox News Sunday" the scenario is technically possible.
If no candidate wins on the first ballot, more delegates will become free agents on each successive ballot.
Here's what Priebus says: "Can someone on a later ballot when most of the delegates are unbound, be nominated? I think they can be. But that would be an extreme hypothetical, I think, and highly unlikely."
John Kasich (KAY'-sihk) says the Republican convention could prove to be civics-lesson time for the country.
The Ohio governor wants to be president but is trailing front-runner Donald Trump and Texas Sen. Ted Cruz as the nominating calendar unfolds — with Wisconsin voting Tuesday.
Kasich's hope is that no candidate gets enough delegates before the GOP convention in July in Cleveland — meaning an "open" convention.
To Kasich, "it's going to be so much fun." He thinks it will hold the country's interest so much that kids will spend less time following the Kardashians and Justin Bieber and more time focusing on "on how we elect presidents."
"It will be so cool," he tells ABC's "This Week."
A lot of debating about a Democratic debate before New Yorkers vote in the presidential primary on April 19.
The Democrats last debated in March and have been negotiating two more debates in April and May. But Hillary Clinton and Bernie Sanders have hectic schedules.
Sanders tells ABC's "This Week" that New Yorkers "deserve to hear us discussing the important issues and that "I suspect it will work out." Clinton says she's confident it will happen and she tells NBC's "Meet the Press" — "I want it."
Sanders says his goal is an option that gives the candidates the largest viewing audience possible.
There'll be nothing "stolen" at the Republican presidential convention this summer.
Amid talk of the Republican establishment trying to block Donald Trump, the party chairman says the nomination process will be clear, open and transparent. Cameras will be there "at every step of the way."
A fight is brewing if no candidate — front-runner Trump or rivals Ted Cruz and John Kasich — has secured the necessary number of delegates during the primary contests.
GOP Chairman Reince Priebus (ryns PREE'-bus) tells ABC's "This Week" that if the race isn't settled, "we're going to have a multi-ballot convention." In each round of voting, more and more delegates are free to pick a candidate of their choice.
But Priebus is clear: "Nothing can get stolen from anyone."
