Scott Stringer last night called a Bronx lawmaker an “a–hole” for backing rival Eliot Spitzer in the Democrat race for comptroller, The Post has learned.
The confrontation between Stringer and state Assemblyman and former Bronx Democratic chairman Jose Rivera occurred outside a Riverdale concert featuring Dionne Warwick.
Spitzer had just left the event and Stringer was entering it when Rivera said he offered to shake the Manhattan borough president’s hand.
“Stringer told me, `You’re an a**hole’. I was stunned,” Rivera said.
“Scott also said, `I’ll see you after I win,’” Rivera said.
Most of the Bronx Democratic Party establishment — including Hispanic leaders like Borough President Ruben Diaz Jr. — are supporting Stringer. But Rivera endorsed Spitzer.
“I’ve never experienced anything like this in all my years in politics. Now I’m motivated to go all out for Eliot Spitzer,” Rivera said.
A Stringer spokeswoman said the candidate didn’t remember dropping the A-bomb — but didn’t deny it.
Meanwhile when local Sen. Jeff Klein announced that the two candidates had attended the event, Stringer got more cheers and Spitzer more boos, a source said.
