Video report by ITV News Senior International Correspondent John Irvine
A redacted version of the Mueller Report which states there was insufficient evidence to prove Donald Trump's camp colluded with Russia during the 2016 Presidential election campaign has been released.
Prior to its public release, Mr Trump declared, with a Game of Thrones themed meme, "Game Over" on the investigation conducted by Robert Mueller.
In response HBO asked the US President to cease using its intellectual property for "political purposes".
US attorney general William Barr said there was “no collusion between the Trump campaign and Russian government hackers”.
Mr Trump told reporters: "This should never happen to another president again."
However, on Friday, Jerry Nadler, the chairman of the US House of Representatives Judiciary Committee issued a subpoena for the full report and the underlying materials.
Democratic Jerry Nadler of New York is asking for the information by May 1.
That is also the day when Attorney General William Barr is scheduled to give evidence before a Senate committee and one day before Mr Barr is set to appear before Mr Nadler’s committee.
The subpoena is the opening shot in what could be a lengthy legal battle.
If the Justice Department does not respond, Democrats could hold officials in contempt of Congress or eventually fight the battle in court.
The Judiciary Committee voted 24-17 earlier this month to give Mr Nadler permission to issue subpoenas for the final report, its exhibits and any underlying evidence or materials prepared for Mr Mueller’s investigation.

What we know about the Mueller Report
Mr Mueller investigated 10 separate actions by President Trump to see if he aimed to obstruct justice but failed to reach a conclusion. However, he did find a concerted effort by Russia to interfere with the 2016 election but no criminal conspiracy between the Trump camp and Russia. "While the investigation identified numerous links between individuals with ties to the Russian government and individuals associated with the Trump campaign, the evidence was not sufficient to support criminal charges."
“Oh my God. This is terrible. This is the end of my presidency. I’m f*****,” the President remarked after learning that Mr Mueller has been appointed to lead the investigation.
Mr Trump tried to get Mr Mueller fired. In June 2017 the President contacted Don McGahn in attempt to get Mr Mueller removed from his role due to an alleged "conflict of interest".
Although Mr Mueller's investigation has come to an end, he says 14 spin-off inquires have started due to his work
Speaking at a White House event for wounded troops, Mr Trump says he was vindicated by the report
Mr Trump tweeted 'Game Over' with a reference to Game of Thrones as part of a meme created for the event. TV channel HBO, who produce Game of Thrones, have asked the President to no longer use the show's intellectual property in his social media output.

What questions remain...
Will the Democrats look to impeach the President? Despite the President being cleared of any direct collusion with Russia, some Democrats say Mr Trump still deserves to be removed from power
Will Attorney General Barr resign? "You can be the President's defence attorney or America's attorney general, but you can't be both," Rep Eric Swalwell - a 2020 Democratic presidential hopeful - said in a statement.
Why was so much of the Wikileaks reporting redacted? It is thought this could be due to the fact that the trial of former Trump adviser Roger Stone Jr is ongoing.
What relevant information was deleted by members of the Trump campaign? "The investigation did not always yield admissible information or testimony, or a complete picture of the activities undertaken by subjects of the investigation," the report said, acknowledge that certain people deleted communications that could have been deemed relevant.
Mr Barr said the president did not exert executive privilege to withhold anything in the report. And he said the president’s personal lawyer had requested and gotten a chance to review the report before its public release.
Critics of Barr, mostly Democrats, condemned the attorney general for apparently acting like a defender of Trump.
Massachusetts senator Elizabeth Warren tweeted it was "a disgrace" for Barr to act like "the personal attorney and publicist" for Trump.
