UPDATE: May 29 10:30 a.m.

We received the following e-mail response from Ryan Rudominer, national press secretary for the DCCC: "You don't need to contribute to win the contest. We are not accepting money from lobbyists for this fundraiser."

(Click on the invitation below to see the contest he refers to.)

The Democratic lobbyist who received the invitation/solicitation and told us about it had this to say: "They know damn well that this is Hillary's old mailing list, which includes every DEM lobbyist in the entire freakin' world who gave her money."

Here is the original post: 

Oops! Someone at the Democratic Congressional Campaign Committee forgot to scrub a very important, and sensitive, e-mail/donor list.

You see, at least one lobbyist (who contacted us) -- and no doubt many others -- received an invitation from the DCCC and James Carville to make a contribution to the committee for a June 18 fundraising dinner in Washington that will include President Obama.

See invitation here: 

The president has instructed the DCCC (and the Democratic Senatorial Campaign Committee) they are not to solicit contributions from lobbyists and political action committees for these types of events.

But the Carville-DCCC invitation was sent to members of HillaryClinton.com's online community. Hillary Clinton had no prohibition on taking K Street-connected money when she was running against Obama for the Democratic nomination.
