Rabbi Yaakov Yagen went to ground around December of 2012 when Nechemya Weberman testified that he originally sent his girls to Yagen (in Weberman’s appartment). but then the vaad decided to use Weberman himself. His website stopped listing events and he cancelled many speaking engagements. Even now, the calender on his website is completely empty.
Last night he reappeared to give a talk at the Safra shul in Miami. During Q & A he said he spent most of this time in Israel on “business” which he will only describe as “this and that.” He also says he was in Israel to perform a wedding. What a tzadik! He went to a country suffering a severe rabbi shortage to help out.
