Lieberman's "Mea Culpa"

From today's kumbaya moment, Lieberman on statements he made about Barack Obama:

And in that regard, I said very clearly, some of the statements, some of the things that people have said I said about Senator Obama, are simply not true. There are other statements that I made that I wish I had made more clearly and there are some that I made that I wish I had not made at all. And obviously in the heat of campaigns, that happens to all of us, but I regret that and now it's time to move on.

Can we get a breakdown on this? Which statements didn't he really make, which ones were unclear, and which ones does he regret?
