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):

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.
