Daniel Craig has shown his financial support for US presidential candidate Bernie Sanders - but it appears he may have been 'duped'.

According to reports, the Spectre star donated almost $50,000 to Americans Socially United, but concerns have been raised about the super PAC's legitimacy.

Both Variety and the New York Times note that the Center for Public Integrity has revealed doubts about their integrity and that of its founder Cary Lee Peterson.

The report - which says Craig donated $47,000 in July - points to his alleged issues, including outstanding warrants in Arizona and money owed to creditors.

Meanwhile, Sanders' own campaign has asked him to stop his cause - which uses names like Bet on Bernie and Ready for Bernie Sanders 2016 - and spoke out about the role of 'super PACs'

In a statement to Variety, Craig said: "I made a donation to this organisation in good faith as I understood it to support Senator Sanders' candidancy.

"Currently, I have been informed of no evidence to question that my donation has not been used as intended. Should that situation occur, then clearly, I will review my position."

Speaking to the Center for Public Integrity, Peterson insisted he set up the PAC because of he believes "in the cause".

he added that the group had already spent more than $1million on field organisers, billboards and materials supporting Sanders.
