Republican Bob Bishop is dropping out of the Race for the 19th Congressional District, his campaign confirmed Tuesday.

He will withdraw his candidacy ahead of the federal primary in June, and says he will instead back John Faso for the seat.

“John Faso has shown us that he has what it takes to best represent our interests,” Bishop said in a statement. “Not only does John have the endorsement of four parties critical to winning in November, he also possess the skills and passion needed to win this race. It is time for all Republicans and Conservatives to unite behind John Faso in order to continue Congressman Gibson’s strong legacy while making sure this seat does not fall into the hands of a radical liberal like Zephyr Teachout.”

UPDATE: Faso thanked Bishop for his endorsement after the announcement Tuesday.

“I am very grateful for Bob Bishop’s support in this race, and I salute all the hard work he’s done over the past several months to voice important local economic and agricultural concerns that we share,” Faso said. “Bob’s endorsement is a meaningful one, and I look forward to his friendship and counsel both as a candidate and as a member of Congress. “

Bishop had come under scrutiny from his now-former primary opponent Andrew Heaney in recent weeks over ballot signatures. Heaney and Bishop were scheduled to appear in court to resolve the litigation this Friday.  Heaney’s campaign issues a statement later Tuesday responding to Bishop’s departure.

“Now voters will have a clear choice between John Faso, a 30 year lawyer-lobbyist and failed Albany politician versus Andrew Heaney a political outsider and conservative small businessman who wants to change the corrupt culture in Washington, DC.,” Heaney said.

Bishop’s decision narrows the Republican field in the 19th Congressional District to two candidates ahead of the primary – Faso and Heaney. Former Gubernatorial candidate Zephyr Teachout will compete against Livingston Deputy Town Supervisor Will Yandik on the Democratic side.

The primary will be held June 28.
