Bernie Sanders took a shot at Hollywood on Sunday, calling two upcoming Hillary Clinton fundraisers organized by George Clooney 'obscene'.

The actor is hosting a fundraising dinner for the Democratic candidate in San Francisco on April 15, where two seats at the head table with Clinton, Clooney and his wife Amal cost $353,400.

The following night, Clooney is hosting yet another event at his home in Los Angeles where tickets are $33,400 each.

Bernie Sanders on Sunday slammed Hillary Clinton for 'going to big-money people' like George Clooney to fund her campaign

'It is obscene that Secretary Clinton keeps going to big-money people to fund her campaign,' Sanders said on CNN's State of the Union on Sunday.

'I have a lot of respect for George Clooney. He’s a great actor. I like him,' Sanders continued. 'But this is the problem with American politics … Big money is dominating our political system. And [my supporters and I] are trying to move as far away from that as we can.'

'So it’s not a criticism of Clooney. It’s a criticism of a corrupt campaign finance system, where big money interests - and it’s not Clooney, it’s the people coming to this event - have undue influence on the political process.'

Sanders campaign has largely been funded by small donations and he says tickets to his events usually just cost '$15 or $50' to get into.

'It’s not only this Clooney event,' Sanders said. 'It is the fact she has now raised well over $15 million from Wall Street for her super-PAC, and millions more from the fossil fuel industry, and from the drug companies.'

Despite winning both the Alaska, Washington and Hawaii primaries on Saturday, Sanders is currently tailing Clinton by more than 700 delegates.

But he believes he can make up ground in June during the California primary where 475 delegates are at stake.
