Trump says prosecutors have found no evidence of Russia collusion

US President Donald Trump said on Saturday prosecutors had found no evidence of collusion with Russia despite a lengthy and costly investigation into allegations of Russian interference in his 2016 presidential election campaign.

A day after US prosecutors detailed a previously unknown attempt by a Russian to help the campaign, Trump tweeted: “After two years and millions of pages of documents (and a cost of over $30 million) no collusion!”

Russia has denied interfering in the election to help Trump.
