Yes, but he is disputing the alcohol. I think the truth on that one will come out. Even the MSM will hunt down the facts there - they have to or lose even more of their credibility. But driving around after taking sleeping medication - even on it's own without the alcohol or other meds - that bad enough on its own.
The more basic point: why is Rep. Kennedy driving around at 2:45 in the morning, while doped up on sleeping pills and anti-nausea drugs?
His story, such as it is, does not make sense.
