UPDATE: 10:30 p.m. EDT -- U.S. Sen. Ted Cruz was the big winner Saturday as several states allocated delegates at their Republican Party conventions.

But Cruz's rival, Donald Trump, and his supporters were reportedly fighting mad after Cruz bested Trump in Arizona, even though Trump had previously won the state's primary election.

In fact, Trump's Arizona campaign chairman, Jeff DeWit, said the campaign plans to file a lawsuit over the results, in which Trump lost about 40 of the 55 delegates up for grabs in Arizona, Politico reported.

"This stinks to high heaven!" DeWit shouted at reporters, decrying the results, as the Arizona Daily Star reported.

Republicans in Arkansas, Alaska, Massachusetts, Missouri and Virginia also allocated delegates Saturday, with Cruz winning about 80 of the more than 170 total slots up for grabs, Politico reported.

Aside from Trump, other delegates were allocated to Ohio Gov. John Kasich, and Florida Sen. Marco Rubio, who ended his candidacy March 15.

UPDATE: 8:35 p.m. EDT -- U.S. Sen. Ted Cruz won 10 of the 13 at-large delegates up for grabs Saturday at Virginia's Republican Party convention in Harrisonburg, the Washington Post reported. The remaining three delegates went to Donald Trump, with Ohio Gov. John Kasich receiving none.

But Cruz’s victory matters only if he can prevent Trump from clinching the nomination before the convention, the Post reported.
