From NYTimes:
Rabbi Chaim Dovid Zwiebel, executive vice president of Agudath Israel of America, an Orthodox umbrella group, said Mr. Tischler was a fringe figure who had “made an idiot of himself.”
“I don’t think anybody really knew him or had heard of him until he decided to turn himself into the wonderful spokesman he thinks he is,” Rabbi Zwiebel said. “This guy is supposed to be a community leader? Please. It is an embarrassment.”
