As stated above, the Bar Mitzvah, itself, is automatic, and it doesn't need any rabbinical intervention whatsoever.
However, I see that you said specifically, Bar Mitvah "honor". Depending on what that honor was, under certain circumstances, it can, of course, be revoked. For example, if the rabbi said praises about Mr. Kushner, during his Bar Mitzvah, he could publicly renounce what he said, then. If he presented Jared with a siddur or Chumash at his Bar Mitzvah, he could request that they be returned.
So, technically, tangible things such as these can be revoked. I don't see the point to doing this, but, I guess if the rabbi (I assume that there was just one, so I don't know what Mike Rappaport means by using the plural form) wants to make a silly point, to amuse Michael (I don't think Jared would be that amused, but, who knows?) that rabbi is able and welcome to do so.
