>>>I heard from a talmid that Rav Hutner didn’t visit the kosel because he agreed with the satmar rov on it being a problem of not being mechazek the reshoim.
None of his other Talmidim seem to have heard or believe that . They all daven by the kosel . It is inconceivable that someone like Rav Ahron Schechter would have made a public preannounced tefila asifah by the kosel had Rav Hutner opposed going there
Perhaps you are right that he didn’t “visit” the kosel as you put it. He went there to daven.
It’s nice to see you consider Rav Hutner to be deah. Hie had a lot more of a personal connection to and learned a lot more from Rav Kook than the Satmar Rebbe
