It puzzeled me for quite sometime: How come that Michael let the Senator come out so easily? That SOB said unspeakable things about the family... true, he got a "message" that reminded him who were his friends - but still (we know that Michael eliminated ALL his enemies at the end of GF2)...
Besides he sits in the famous Senate hearing and then leaves... I simplly don't get it...
