Sanders supporters shower Clinton motorcade with $1 bills

Supporters of Democrat presidential hopeful Bernie Sanders "made it rain" on Hillary Clinton's motorcade as it passed en route to a high-dollar fundraiser at actor George Clooney's Los Angeles home, throwing $1 bills into the air.

The group of about 75 Sanders supporters were outside a counter-fundraiser being held on Saturday at the residence of one of Clooney's neighbours, NBC News reported.

Demonstrators held signs up as speakers from that home blared the chorus, "We're in the money", and threw cash at one of the vehicle as it passed.

Sanders has slammed Clinton over what he has called her close ties to Wall Street and paid speeches, and the Vermont senator often refers his average donation size of $27 as an example of his distance form big-money politics.

Attendees at the Sanders event paid $27 per person.

Attendees for the event with Clinton gave at least $33,400 per person. Co-hosts gave $100,000 per couple.

Clooney said in an interview with NBC News' "Meet the Press" that he agreed with Sanders' criticism of such fundraisers as "obscene".

"Yes. I think it's an obscene amount of money ... The Sanders campaign, when they talk about it is absolutely right. It's ridiculous that we should have this kind of money in politics. I agree completely," Clooney said.

But he also said the money is necessary to get Democrats elected.
