Donald Trump Jr was approached last summer by a publicist, Rob Goldstone, acting on behalf of a Russian lawyer, Natalia Veselnitskaya, who offered the Trump campaign ‘very high level and sensitive information’ about Hillary Clinton’s dealings with Russia. The response by Donald Jr was not high-minded: ‘If it’s what you say, I love it.’ Apparently the offer of information turned out to be an empty pretext. The instigator of the meeting was a pop musician, Emin Agalarov, the son of a businessman, Aras Agalarov – a name that also came up in the ‘dodgy dossier’ on Trump collected by the ex-MI6 agent Christopher Steele. Trump Senior had taken money from Agalarov, and in return provided Miss Universe contestants for use in a music video by Emin. American billionaires and Russian oligarchs may be supposed to share an elective affinity. They are members of an international tribe, and snap their fingers at sovereignties.
