Rumor has it that R' Malkiel did it in exchange for the "Kusher Rotunda" at BMG
While I would be more then happy to poke fun at that rotunda .Not that taking it down and returning the money wouldn't be the high road.
High road? His son goes off the derech so you can't take his money? Is that a joke?
There is a huge difference between a "rabbi" doing that conversion, and the private family matter of how to accept it/not accept it. A mosad may have the responsibility to not take money from Jared, but from his father?!?!
