Huff Post reports on a story that I knew of last week, but wasn’t going to report until and unless it was confirmed. They appear to have done just that:

One of Sen. Hillary Clinton’s top financial supporters offered $1 million to the Young Democrats of America during a phone conversation in which he also pressed for the organization’s two uncommitted superdelegates to endorse the New York Democrat, a high-ranking official with YDA told The Huffington Post.

Haim Saban, the billionaire entertainment magnate and longtime Clinton supporter, denied the allegation. But four independent sources said that just before the North Carolina and Indiana primaries, Saban called YDA President David Hardt and offered what was perceived as a lucrative proposal: $1 million would be made available for the group if Hardt and the organization’s other superdelegate backed Clinton….

Saban is the nation’s largest political campaign contributor over the last decade, FEC records show, giving nearly $13 million since 1999 to dozens of candidates, PACs, and Democratic campaign committees….

In March, high-ranking donors for Sen. Clinton, including Saban, sent a letter to House Speaker Nancy Pelosi chastising her for suggesting that superdelegates had a responsibility to support the candidate who finished the primary process leading in the pledge delegate count.
