WASHINGTON (AP) — The latest on the race for the Republican and Democratic presidential nominations a day after critical primaries in five states (all times local):

10:25 p.m.

Former House Speaker John Boehner says he’d support his successor, Wisconsin’s Paul Ryan for president if Republicans cannot nominate any candidate at their national convention this summer.

Boehner, who has endorsed John Kasich, tells the Futures Industry Association that if Republicans can’t agree on the first ballot to nominate Donald Trump, Kasich or Texas Sen. Ted Cruz, he’s “for none of the above.”

Boehner adds, “They all had a chance to win. None of them won. So I’m for none of the above. I’m for Paul Ryan to be our nominee.”

The comments were first reported by Politico.

Boehner spokesman Dave Schnittger is responding that Boehner’s “His off-the-cuff comments this morning were about a hypothetical scenario in which none of the current candidates are able to secure the nomination at the convention.”

8:44 a.m.

Donald Trump says he will not participate in the next GOP presidential debate on Monday in Utah because “we’ve had enough debates.”

The front runner for the Republican presidential nomination said Wednesday on Fox News that he’s committed to a big speech the same night.

Trump says he didn’t know about the March 21 event until Tuesday night, when he won critical primaries in Illinois, North Carolina and Florida.

Without Trump, the only two onstage would be Ohio Gov. John Kasich, who won his home state in the same contests Tuesday, and Texas Sen. Ted Cruz. It would be a clash of potential alternatives as each man maneuvers to claim the mantle of credible alternative to the brash billionaire who has controlled the race for months.

7:57 a.m.

Donald Trump says Republican senators who are trashing him in public are calling him in private because they want to “become involved” in his presidential campaign, eventually.

Trump didn’t name any senators in his interview on MSNBC the morning after his wins in Florida, Illinois and North Carolina Tuesday night. But he said the Republicans include some who appear on the morning talk shows saying, “Donald Trump, we have to stop him.” Trump added that they “are calling me to work out a deal” to “become involved. They see things here that they’ve never ever seen in the Republican Party.”

7:33 a.m.

Republican presidential front-runner Donald Trump says that if the GOP tries to deny him the party’s nomination even if he’s within reach of sufficient delegates at convention time, “We’d have riots.”

Trump tells CNN’s “Newsday” Wednesday morning he’s brought large numbers of people into the party — “The really big story is how many people are voting in these primaries,” — and he says “if you just disenfranchise these people, I think you would have problems like you’ve never seen before.”

He tells anchor Chris Cuomo, “I wouldn’t lead it,” but said unrest could happen.

Trump cited a hypothetical scenario where he’d go to the Cleveland convention in July with roughly 1,000 delegates and a rival would show up there with 500.

He said he believes he will nail down the nomination before the convention and said he couldn’t imagine failing to get the party’s nomination virtually “automatically” in such a scenario. Trump said “I don’t even want to think about” what he’d do if he’s in such an advantageous position but still does not become the nominee.

7:13 a.m.

John Kasich says his home state victory Tuesday night dealt Donald Trump a “very, very big blow” to getting the number of delegates required to win the GOP presidential nomination. He tells NBC’s “Today” that winning Ohio makes the case that neither Trump nor Texas Sen. Ted Cruz can “come into Ohio with the philosophies they have and win. And if you can’t win Ohio, you can’t be president.”

Kasich has won no other states and lags far behind Trump and Cruz in delegates. But Kasich predicts that “nobody is going to have enough delegates” by the time of the Republican National Convention this summer to win the nomination outright.

7:00 a.m.

The math and momentum point to a Republican presidential nomination for Donald Trump after high-stakes primaries in five states, as GOP officials grapple with whether to embrace the billionaire businessman or rally behind a longshot alternative.

Democrat Hillary Clinton strengthened her position against Bernie Sanders with primary victories in Florida, Illinois, Ohio and North Carolina on Tuesday, putting her in a commanding position to become the first woman in U.S. history to win a major-party nomination.

Trump strengthened his hand with wins in Florida, North Carolina and Illinois but fell in Ohio to that state’s governor, John Kasich. Votes were also being counted Tuesday in Missouri, though races in both parties were too close to call.

Florida Sen. Marco Rubio ended his once-promising campaign after a devastating home-state loss.
