Elsewhere in his statement Mr Mueller praised his staff’s “fair and independent” approach to the investigation, saying they had the “highest integrity” – a marked difference to Mr Trump who has called his team “angry Democrats”.
Mr Mueller also declined to lean into a row that flared up between himself and William Barr, the US attorney general. Mr Mueller had urged the latter to publish chunks of the report earlier than he had.
Mr Mueller said he appreciated that almost all of the report was eventually published and added: “I do not question the attorney general’s good faith in that decision.”
He also pushed back on Democrats demanding he testify before Congress, saying: “The report is my testimony.” However Democrats yesterday said they would continue to seek his appearance.
Mr Mueller finished with a call for Americans – and perhaps lawmakers and government officials – to take seriously the Russian election meddling he had uncovered.
“I will close by reiterating the central allegation of our indictments – that there were multiple, systematic efforts to interfere in our election. That allegation deserves the attention of every American,” he said.
Mr Mueller took no questions from the press.
Sarah Sanders, the White House press secretary, said: “The Special Counsel has completed the investigation, closed his office, and has closed the case.’
