Who Paid for Pelosi's Party?

As we reported earlier this week, Nancy Pelosi planned to hold a special reception on Capitol Hill this afternoon to celebrate the "accomplishments" of the 111th Congress.  So who footed the bill for the event?  According to Politico, the outgoing House Speaker's office isn't saying:

The event, according to an invitation obtained by POLITICO, was in the Cannon Caucus Room Wednesday afternoon. It was closed press, and invited guests were “advocacy groups.”

When asked who paid for it, Nadeam Elshami, a spokesman for the California Democrat, declined to reveal who was footing the bill.

“No taxpayer funds or lobbyist money paid for the meeting,” Elshami said in an email to POLITICO.

When pressed further, Elshami said “No taxpayer or lobbyist. What more do you want?”
