Donald Trump Calls Ted Cruz and John Kasich Alliance 'Desperate!'

In a final effort to defeat Donald Trump, Ted Cruz and John Kasich have teamed up to take down the GOP front-runner.

Cruz's campaign manager released a statement Sunday night, claiming his campaign would "focus its time and resources in Indiana and in turn clear the path for Governor Kasich to compete in Oregon and New Mexico."

Kasich's team then put out a similar statement, saying they would "give the Cruz campaign a clear path in Indiana."

The two candidates joining forces signals a change in sentiment toward one another, as Cruz has criticized Kasich for being a "spoiler" candidate and that "a vote for John Kasich is a vote for Donald Trump."

Trump took no time to call out Cruz and Kasich in a tweet, calling their alliance "desperate" and "sad."

"Lyin' Ted and Kasich are mathematically dead and totally desperate," Trump wrote. "Their donors & special interest groups are not happy with them. Sad!"

In a statement released by his campaign, Trump also said, "It is sad that two grown politicians have to collude against one person who has only been a politician for ten months in order to try and stop that person from getting the Republican nomination."

Currently in the lead, Trump has accumulated 845 delegates, with Cruz holding 559 and Kasich with 148, less than Marco Rubio, who has dropped out of the race for the presidency. Echoing his lead, Trump said Cruz is currently in "free fall" and that he does not "react well under pressure."

The billionaire presidential candidate said the alliance has made him more "determined for the good of the Republican Party and our country, to prevail!"
