Donald Trump called out John Kasich at a campaign rally in Rhode Island on Monday afternoon.
The GOP frontrunner unveiled a new nickname for Kasich, calling the Ohio governor “1 for 41 Kasich.”
The name refers to the number of states Kasich has won during primary season thus far.
In a statement on Monday, Trump said: “Governor Kasich, who has only won 1 state out of 41, in other words, he is 1 for 41 and he is not even doing as well as other candidates who could have stubbornly stayed in the race like him but chose not to do so."
Trump also mocked the way Kasich eats.
“Did you see him? He has a news conference, all the time when he's eating. I have never seen a human being eat in such a disgusting fashion," he said during the rally.
Earlier in the day, Trump was calling Kasich “1 win and 38 losses.” By the afternoon, he changed the number of of times his rival lost primary elections.
The attacks on Kasich come after he and Ted Cruz announced they are joining forces to stop Trump from winning the Republican presidential nomination.
On Sunday evening, both camps released statements to say they will focus on different states during upcoming primaries to keep Trump out.
Kasich will pull out of Indiana to give Cruz "a clear path" in the May 3 primary, they said. Cruz will "clear the path" for Kasich in Oregon for its May 17 primary and New Mexico for its June 7 primary.
They hope that these efforts will block Trump from gaining the 1,237 delegates he needs to take the nomination. So far he has 845 delegates to Cruz's 559 and Kasich's 148.
Trump responded to the alliance in a tweet: “Shows how weak and desperate Lyin' Ted is when he has to team up with a guy who openly can't stand him and is only 1 win and 38 losses."
