Mayor R.T. Rybak isn't running for re-election this year, but it hasn't stopped his fundraising.

The mayor's political action committee, which was registered last December, is hosting a fundraiser Saturday night at a home in downtown Minneapolis.

"RyPAC" allows the mayor to raise money for state campaigns, but Rybak offered few details in December about its exact purpose.

A source close to the mayor said the event is not intended to raise money for another Rybak campaign – the mayor has been mum about his future aspirations.

The more likely beneficiaries would be legislators who voted in favor of the same-sex marriage legislation, the source said.

The fundraiser coincides with the completion of Aquatennial – not the first time Rybak has raised money during the event. It will feature a view of the fireworks over the Mississippi River. Suggested donations are $50, $75 and $100.
