In a New York Post Story Bronx Assemblyman (and former Bronx Democratic County Leader) Jose Rivera claims that Manhattan Borough President and candidate for City Comptroller Scott Stringer called him an "Asshole" for supporting Eliot Spitzer for City Comptroller. This is reported to have happened before the Dionne Warwick concert that took place in Seton Park in the Riverdale section of the Bronx.
I saw Assemblyman Rivera with his close political advisor Mr. Mike Nieves (a former Queens council candidate this year) with Spitzer for Comptroller material, but this was after Spitzer had left, and before Stringer arrived to the Warwick concert. I also saw both Assemblyman Rivera and Mr. Nieves at the opening of 15th City Council candidate Albert Alvarez"s campaign office that is doubling as a Spitzer for Comptroller site. Alvarez was Chief of Staff to Assemblyman Rivera's son Joel Rivera for his 12 years as the councilman from the 15th district.
