According to this report, Forward editor J.J. Goldberg:
[L]et the crowd in on a detail never published before. When the Senate held a special hearing on Pell grant fraud, every single name on the list was a chassidishe or yeshivishe figure. Someone gave the list to the ADL, whose Abe Foxman called John McCain to complain that it looks like an anti-Semitic witch hunt and that neo-Nazis will have a field day with it. John McCain wrote back that he cannot help that only Yidden committed fraud, so the hearings will continue.
