Republican Rep. John Faso shrugged off on Monday news of a challenge from a former aide to Gov. Andrew Cuomo, saying in an interview with Spectrum News he’ll “turn to politics when the time comes.”

Gareth Rhodes is the latest Democrat to declare in the race for the 19th congressional district against Faso.

“I’m taking this step not only because we need to fight back against self-interested politicians like Faso and Trump, but because I believe we need a new generation of leaders to step up and fight for the communities that raised them,” Rhodes wrote in an essay posted to Medium.

The seat has been a hotbed for competitive congressional races since 2012. Faso first took office this year, holding the seat for the GOP against Democrat Zephyr Teachout.

“The election is about 20 months away,” Faso said. “I was just elected five months ago.”

But Faso has come under fire from liberal advocacy groups after backing the passage in the House of Representatives of the American Health Care Act, the bill that would dismantled the Affordable Care Act.

Faso has drawn the ire of Cuomo for the provision in the bill that would shift the burden of Medicaid costs from county governments to the state.

“That costs the average homeowner in Ulster County about $500 a year,” Faso said in the interview. “New York finally has to fix it and after 2020 they’ll be required to.”

At the same time, Faso is being goaded into holding a town hall event in his district. Democratic Rep. Sean Patrick Maloney, who represents a neighboring House district, is appearing at the event today in Faso’s district.

“This is a political exercise,” Faso said. “Unfortunately Congressman Maloney is engaged in a political stunt. This is a partisan political exercise so, no, I’m not going there.”
