It is getting more interesting all the time....
From their response, it sounds like Comcast is going to give Senator Leahy the corporate equivalent of the middle finger salute. The blow-off is already starting by dismissing the Senator's inquiry: She pointed out that Senator Leahy isn't on the committee for deciding either the Time Warner Cable merger or net neutrality rules, since that is a decision for the FCC and Department of Justice. She also noted that it was unusual for the senator to target Comcast alone out of all the ISPs.
I suppose that even if they did tell him "yes", they would refute it later by saying "he doesn't count as he's on the wrong committee" or "we had our fingers crossed..pfffftttt".
