Mikehall, he isn’t controversial to me. I grew up in his shul 😀
But to the Yeshiva World, he IS controversial. Yes, Rabbi Tendler learned with Rav Moshe Feinstein and yes he approved of the shidduch.
It doesn’t change the fact that Rabbi Tendler often publicly disagrees with R’ Elyashiv. For the most part, the Yeshiva World holds R’ Elyashiv in much higher regard than Rabbi Tendler.
