The party that Rob Astorino helped found in 2014 is endorsing his Democratic opponent in this year's race for Westchester county executive.
Curtis Sliwa, the chairman of the state Reform Party, said his party is endorsing State Sen. George Latimer in the race.
Astorino, who is running for a third term, founded the party in 2014 as the Stop Common Core Party when he unsuccessfully ran for governor, later changing its name. Sliwa took control of the party in 2016 in a move that has been challenged in court.
Sliwa, who founded the Guardian Angels told The Daily News that Astorino had drifted away from the Reform Party Platform and the party will no longer be a rubber stamp for the Republican Party.
Bill O'Reilly, a spokesman for Astorino's campaign, said Astorino is the true champion for government reform.
"He's never once raised taxes," O'Reilly said. "County government spends less than it did when he first came into office; Westchester now has its own term limits, and Astorino is now finding ways to produce revenue for key infrastructure improvements so that taxpayers don't get stuck with the bill going forward."
Latimer said he was honored to receive the Reform Party's endorsement.
"I've long advanced true reform of government," Latimer said. "It's clear that Rob Astorino simply does not represent the values of civic participation, transparency, and oversight that the Reform Party is committed to defending in our elections."
Latimer faces Legislator Ken Jenkins in a September primary.
