That is a cooked up alibi, and everyone knows it. She is telling reporters she was with him, and will sign an affidavit saying "he wasn't drinking that night."
The Kennedy liars (lawyers) and spin artists have finally decided upon a strategy.
1. Get him into rehab ASAP to deflect attention from the DUI and to elicit sympathy from any judge this may come before.
2. Destroy any evidence out there they can (credit card statements at the bars, etc).
3. Cook up an alibi to support their lies.
4. Pay off and/or threaten any witnesses who may come foward with the truth.
I am sure by now that the two employees at the bar were mistaken......they were unavailable for comment, both are on vacation to Bermuda...
Cooking up an alibi is not always a smart thing to do. If you do that and they break your alibi you are dead meat.
