Donald Trump called for Ohio governor John Kasich to drop out of the presidential race.
During a speech in Wisconsin, Trump said that it was unfair for Kasich to continue his campaign considering he's only won his home state's primary.
"If I didn't have Kasich, I automatically win," Trump said in Allis, Wisconsin, AL.com reported. Trump also told a supporter that "Kasich shouldn't be allowed to continue and the RNC shouldn't allow him to continue."
Both Trump and Ted Cruz are working to block Kasich from appearing on the ballot at the Convention in July.
"I expect the Rules Committee to require a level of support that would leave only two candidates on the ballot at the convention," a Cruz campaign aide told MSNBC.
"The Cruz people and Trump people are fighting hard to make sure their hard-core delegates get on the committee," Trump adviser Barry Bennett added. "We'll be successful getting at least a majority — or supermajority."
Cruz has intensified his efforts to get Kasich to drop out, airing ads against the governor as well as sending out anti-Kasich mailers.
"Right before John Kasich was governor, he collected $611,000 from a Fortune 500 company. After Kasich became governor, that same company received [$619,000] in state tax breaks for job creation but last year the company laid off 100 Ohioans even as its CEO cut a half-million dollar check to Kasich's super PAC. John Kasich: Not for us," Cruz's ad stated.
Kasich's chief strategist John Weaver called the ad "deceptive."
"Ted Cruz is recycling failed Democrat attacks in a desperate effort to smear Gov. Kasich," Weaver said in a statement. He also claimed that Cruz "never helped create any jobs" but "did get a sweetheart loan from Goldman Sachs; a loan that he illegally failed to disclose during his Senate run."
"Cruz's attack and own hypocrisy are further proof that the voters can't trust him and he will do anything to win," Weaver's statement read, ABC News reported.
