A campaign spokeswoman for Rep. Mike McMahon (D-N.Y.) was fired Thursday after pointing to a list of Republican opponent Michael Grimm's Jewish donors as evidence his base of support in the district is thin. 

Campaign spokeswoman Jennifer Nelson told the New York Observer, "There is a lot of Jewish money, a lot of money from people in Florida, Manhattan, retirees."

Nelson e-mailed out a document titled "Jewish Money Q2" to an Observer reporter Thursday. 

The McMahon campaign promptly fired Nelson and in a statement Rep. McMahon said, "Any comments that could serve to divide our community along religious or ethnic lines have no place in our community or my campaign. I sincerely apologize for her comments, and as she has since been terminated from our campaign, there will be no such incidents in the future."

Earlier in the week, New York Democrats targeted Grimm for remarks he made about McMahon in an interview with The Hill.  

“Had he voted for the healthcare bill, Staten Island and Brooklyn, they would really have been marching like they were going for Frankenstein,” Grimm said in the interview. “There was no question. That was just not even an option. Physically, he would have been in danger. It would have been that bad.”

Grimm, a former FBI agent, has won the backing of Sen. John McCain (R-Ariz.) and former Alaska Gov. Sarah Palin in his primary against Michael Allegretti.
