Former Rep. Nan Hayworth on Thursday endorsed one of the Republicans vying to put her old seat back into the GOP column.

Hayworth gave her nod to Republican Phil Oliva in the 18th congressional district, which she represented for a single term from 2011 through 2013.

Hayworth was unseated in 2012 by Democratic Rep. Sean Patrick Maloney, who defeated her in rematch for the Hudson Valley district in 2014.

“Phil Oliva has the right ideas to get our country back on track-and he’ll fight tirelessly and effectively for every single citizen in the Hudson Valley,” said Hayworth. “Phil will provide a compelling contrast to the self-serving, cynical crony politics of Sean Maloney. He will be a true voice of the people and I’ll be doing all I can to help him win.”

Oliva is a top aide to Republican Westchester County executive Rob Astorino, the 2014 GOP nominee for governor, who lost to incumbent Democrat Andrew Cuomo.

Oliva is also the president of the consulting firm Gipper Communications.
