George Clooney is set to arrive in Geneva, a centre for international organisations and business, to raise more money for Barack Obama's re-election campaign.
George raised almost $15 million for the US President's campaign at the actor's Los Angeles home in May.
Organisers in Geneva expect to pull in a more modest amount of about $500,000 fom US donors for Obama's campaign, with many supporters flying in to Geneva from around the world.
Americans Abroad for Obama, the event's sponsor, said on its website that guests are paying $15,000 per person to dine with George, $5,000 US dollars for a photo with him and $1,000 to attend a reception before the dinner. About 30 people are attending the dinner, with about 100 at the reception.
The event is co-hosted by Geneva-based American lawyer Charles C Adams Jr and Matthew Barzun, Obama's campaign finance chairman.
