There was a war of words between Westchester County Executive George Latimer and Mount Vernon Mayor Richard Thomas over renovations of a Memorial Field in Mount Vernon Wednesday.

County Executive George Latimer says he is fighting back against the last ditch effort by Mayor Thomas to change the terms of an inter-municipal agreement between Westchester County and the city, allowing the county to take the lead on renovations of Memorial Field.

"The mayor signing or editing the IMA is irrelevant. The IMA is enforced based on his failure to sign," says County Executive Latimer.

On Tuesday, Mayor Thomas sent out a press release saying he has signed onto to the deal, but county officials say what he tried to do is change the terms of a deal in place without the consent of the county or city council.

"To take a document that has a number of signatories to it, edit it yourself and saying that’s the document is inaccurate," says County Executive Latimer.

Mayor Thomas defended his actions at City Hall on Tuesday, saying he wrote notes onto the already approved contract to prevent city taxpayers from being stuck with a big bill.

"We've done everything we can to protect our taxpayers, I believe the county will go along when they take a hard look," says Mayor Thomas.

However, Latimer insists they will not be going along with the mayor's plan. He says they're sticking to the deal the city council passed last month and added that the mayor changes on the document aren't worth the paper they're written on.

"Everything that distracts from attention on the job is sideshow stuff. What really matters is we fix that field, so you can play ball on it," says County Executive Latimer.

Now that the county has control of Memorial Field, there's no official word on when it plans to start the renovation.
