Donald Trump's campaign is denouncing and severing ties with the chairman of the Ohio Republican Party, Matt Borges.
It's the latest crack in GOP unity in the critical battleground state, where Republican Gov. John Kasich is also not behind the party's presidential nominee. Borges has been openly critical of Trump on several occasions and told some Ohio news outlets he wasn't sure if he would vote for Trump.
Trump's Ohio chairman Bob Paduchik is accusing Borges of undermining Trump as part of a bid to be the next Republican National Committee chair. Borges has been mentioned as a possible successor to Reince Priebus.
Paduchik says in a letter to state committee members that Trump is "very disappointed in Matt's duplicity."
Paduchik says he still expects the Ohio Republican Party to pay the campaign's payroll and expenses in the state.
Borges did not immediately respond to a request for comment.
