Senate Majority Leader John Flanagan insisted Tuesday his endorsement of Sen. John DeFrancisco in the campaign for governor won’t impact his ability to work with incumbent Democrat Andrew Cuomo on the budget.

“Absolutely not,” Flanagan said at a press conference flanked by conference members who had previously publicly backed DeFrancisco. “We’ll have it out and we’ll pass the budget on time.”

Flanagan on Tuesday morning endorsed DeFrancisco, a Syracuse Republican and the deputy majority leader in the state Senate. The nod from Flanagan would not necessarily be unusual if it weren’t for the 2014 election in which Flanagan’s predecessor as majority leader, Dean Skelos, was seen as less-than-enthusiastic about backing the party’s nominee that year, then-Westchester County Executive Rob Astorino.

Flanagan has taken a more assertive posture with Cuomo ahead of the March budget negotiations, challenging the governor’s proposed surcharge and fee increases in the spending proposal.
