"You don't like seniors," offered another agitated attendee.

Many of the angrier exchanges were caught on tape by the local Staten Island news site SILIVE.com and local news channel NY1.

Throughout the evening Grimm persistently defended his positions and attempted to keep the discourse tame. At one point the former FBI agent-turned-congressman warned the most disruptive attendees that if they did not reform their behavior he would have to ask them to leave. 

Grimm also reproved the woman who accused him of wishing to "kill Grandma."

"I want to kill Grandma?" Grimm asked, seeming incredulous. "It’s not respectful to say someone wants to kill Grandma when I spent 16 years of my life putting my life on the line to protect Grandma."

Grimm got his first taste of that feisty atmosphere on his way into the event, when he was greeted by protesters wearing long black frocks, carrying sickles and bearing signs that read "The Grimm Reaper — don't kill Medicare."

Grimm, who was speaking at the Bernikow Jewish Community Center on Staten Island, won his seat in the 2010 election with strong support from Tea Party-affiliated organizations.
