Robert Mueller, who has died aged 81, led an investigation, as US special counsel, into Russian interference in the 2016 White House election and alleged collusion with Donald Trump’s campaign team. Trump was enraged by the two-year-long investigation, which dominated much of his first term as president. He repeatedly dismissed it as a “witch-hunt”.
Mueller’s report, published in 2019, was inconclusive. He found links between Russians and those around Trump, and that his bid for the presidency had benefited from Russian leaks that undermined the Democratic campaign. But he failed to establish collusion on the part of the Trump campaign.
