The Mueller Report is finally being released. But what exactly is it?

Robert Mueller’s report into Russian election interference and Donald Trump’s campaign is finally set to be made public.

The US Justice Department is expected to release a redacted version of the special counsel’s report after a news conference in Attorney General William Barr will reportedly present his own interpretation of the report’s findings.

But what is the Mueller Report?

The report follows Robert Mueller’s investigation into allegations of Russian interference in US elections and involvement in Donald Trump’s campaign.

Put simply, US intelligence agencies believe Russia tried to sway the US Presidential election in favour of Mr Trump.

Robert Mueller was appointed as special counsel to look into whether anyone from the Trump campaign colluded in the effort.

What has it found?

Mr Mueller officially concluded his investigation late last month and submitted the confidential report to the Attorney General. Two days later, Mr Barr sent Congress a four-page letter detailing Mr Mueller’s “principal conclusions”.

In the letter, he said the special counsel did not find a criminal conspiracy between Russia and Trump associates during the campaign, but had not reached a definitive conclusion on whether Mr Trump obstructed justice, instead presenting evidence on both sides of the obstruction question.

Mr Barr said he did not believe the evidence was sufficient to prove that Mr Trump obstructed justice.

What has Donald Trump said about it?

Mr Trump has made his feelings clear in a series of tweets, writing: “The Mueller Report, which was written by 18 Angry Democrats who also happen to be Trump Haters (and Clinton Supporters), should have focused on the people who SPIED on my 2016 Campaign, and others who fabricated the whole Russia Hoax. That is, never forget, the crime.” he tweeted.

Mr Trump and his allies are also attacking the origins of the Russia investigation, portraying it as an effort by Democrats and career officials in the Justice Department who wanted to bring down a president.

He tweeted: “Mueller, and the A.G. based on Mueller findings (and great intelligence), have already ruled No Collusion, No Obstruction,” Mr Trump tweeted. “These were crimes committed by Crooked Hillary, the DNC, Dirty Cops and others! INVESTIGATE THE INVESTIGATORS!”

So what now?

Democrats have already called for Mr Mueller to testify and for his report to be released - which is happening on Thursday.

It won’t be the whole report, the Attorney General has said, which will be redacted to protect grand jury material, sensitive intelligence, matters that could affect ongoing investigations and damage to the privacy rights of third parties.
