AARP state director Beth Finkel says the organization found some comments at the forum it sponsored "unfortunate."
The exchange between 69-year-old Republican candidate George McDonald and the 48-year-old Democrat was caught on camera by the TV station NY1.
After Weiner touched McDonald's chest in greeting, McDonald barked, "Don't put your hands on me ever again."
Weiner responded by telling McDonald he has "anger issues."
When McDonald disagreed, Weiner said, "Yes, you do, Grandpa."
Finkel said Wednesday that a person's age "should not be a factor in politics, or anything else." AARP was formerly known as the American Association of Retired Persons.
