George Clooney has admitted that there is a "ridiculous" amount of money involved in US politics, following criticism of the sums raised at fundraisers.

Clooney hosted two weekend fundraisers in California on behalf of Democratic presidential candidate Hillary Clinton.

Bernie Sanders had earlier described the amount donors were paying as "obscene", though he did not criticise Clooney directly.

Speaking on NBC's Meet the Press, Mr Clooney said that the overwhelming amount of money being raised was not going to support Mr Sanders' rival Hillary Clinton - but to help in the fight to "take back Congress".
