Robert Mueller has spoken out publicly for the first time regarding his team’s conclusions after nearly two years of investigating Russian meddling in the 2016 election — sparking the latest firestorm as Washington and political enthusiasts interpret what the resigning special counsel truly meant to say about Donald Trump and his connection to that election interference.

In a 10-minute speech at Justice Department headquarters, Mr Mueller announced that his team could not clear the president of potential obstruction, but that they did not charge Mr Trump because of department policy.

In response, Mr Trump declared that he had been exonerated once again, noting that he had not been charged. Democrats, meanwhile, are seeing increased pressure to proceed with impeachment hearings against the president.

This is his full statement:

Thank you for being here. Two years ago, the Acting Attorney General asked me to serve as Special Counsel, and he created the Special Counsel’s Office. The appointment order directed the office to investigate Russian interference in the 2016 presidential election. This included investigating any links or coordination between the Russian government and individuals associated with the Trump campaign.

Now I have not spoken publicly during our investigation. I’m speaking out today because our investigation is complete. The Attorney General has made the report on our investigation largely public. We are formally closing the Special Counsel’s office, and as well I’m resigning from the Department of Justice to return to private life. I’ll make a few remarks about the results of our work. But beyond these few remarks it is important that the office’s written work speak for itself.​

Mr Sessions resigned last year, after weathering a contentious relationship with Donald Trump who vocally criticised his attorney general for taking a step back. Mr Sessions recused himself from the oversight citing longstanding Justice Department rules to not be involved in investigations overseeing campaigns that officials were apart of.

Among those crimes, Cohen admitted to facilitating $130,000 in hush money payments to adult film actress Stormy Daniels during the 2016 campaign. Cohen has said he did so at the direction of Mr Trump. Cohen has also admitted that he maintained contacts with Russian officials about a potential Trump real estate project in Moscow for months longer than Mr Trump and others admitted. The talks continued well into 2016 during the campaign, he has said.

Let me begin where the appointment order begins: and that is interference with the 2016 presidential election. As alleged by the grand jury in an indictment, Russian intelligence officers who were part of the Russian military launched a concerted attack on our political system. The indictment alleges that they used sophisticated cyber techniques to hack into computers and networks used by the Clinton campaign. They stole private information and then released that information through fake online identities and through the organisation Wikileaks. The releases were designed and times to interfere with our election and to damage a presidential candidate.

And at the same time as the grand jury alleged in a separate indictment, a private Russian entity engaged in a social media operation where Russian citizens posed as Americans in order to influence an election. These indictments contain allegations, and we are not commenting on the guilt or innocence of any specific defendant. Every defendant is presumed innocent unless and until proven guilty.

The indictments allege, and the other activities in our report describe, efforts to interfere in our political system. They needed to be investigated and understand. And that is among the reasons why the Department of Justice established our office. That is also a reason we investigated efforts to obstruct the investigation. The matters we investigated were of paramount importance and it was critical for us to obtain full and accurate information from every person we questioned. When a subject of an investigation obstructs that investigation or lies to investigators, it strikes at the core of the government’s effort to find the truth and hold wrong doers accountable.

Let me say a word about the report. The report has two parts, addressing the two main issues we were asked to investigate. The first volume details numerous efforts emanating from Russia to influence the election. This volume includes a discussion of the Trump campaign’s response to this activity, as well as our conclusion that there was insufficient evidence to charge a broader conspiracy.

And in a second volume, the report describes the results and analysis of our obstruction of justice investigation involving the president.

The order appointing the Special Counsel authorised us to investigate actions that could obstruct the investigation. And we conducted that investigation and we kept the Office of the Acting Attorney General apprised of the progress of our work.

And as set forth in the report after that investigation, if we had had confidence that the President clearly did not commit a crime, we would have said so.

We did not, however, make a determination as to whether the president did commit a crime. The introduction to the volume two of our report explains that decision. It explains that under long-standing Department policy, a President cannot be charged with a federal crime while he is in office. That is unconstitutional. Even if the charge is kept under seal and hidden from public view, that too is prohibited. The special counsel’s office is part of the Department of Justice and by regulation it was bound by that Department policy. Charging the president with a crime was, therefore, not an option we could consider.

The Department’s written opinion explaining the policy makes several important points that further informed our handling of the obstruction investigation. Those points are summarised in our report, and I will describe two of them for you. First, the opinion explicitly permits the investigation of a sitting President because it is important to preserve evidence while memories are fresh and documents available. Among other things, that evidence could be used if there were co-conspirators who could be charged now. And second, the opinion says that the Constitution requires a process other than the criminal justice system to formally accuse a sitting President of wrong doing. And beyond Department policy we were guided by principles of fairness. It would be unfair to potentially — it would be unfair to potentially accuse somebody of a crime when there can be no court resolution of the actual charge.

So that was Justice Department policy. Those were the principles under which we operated and from them we concluded that we would not reach a determination, one way or the other, about whether the President committed a crime. That is the office’s — that is the office’s final position, and we will not comment on any other conclusions or hypotheticals about the President.

We conducted an independent criminal investigation and reported the results to the Attorney General, as required by Department regulations. The attorney general then concluded that it was appropriate to provide our report to Congress and to the American people. At one point in time I requested that certain portions of the report be released. The Attorney General preferred to make that — preferred to make the entire report public all at once, and we appreciate that the Attorney General made the report largely public. And I certainly do not question the Attorney General’s good faith in that decision.

Now I hope and expect this to be the only time that I will speak to you in this manner. I am making that decision myself. No one has told me whether I can or should testify or speak further about this matter. There has been discussion about an appearance before Congress. Any testimony from this office would not go beyond our report. It contains our findings and analysis and the reasons for the decisions we made. We chose those words carefully and the work speaks for itself. And the report is my testimony. I would not provide information beyond that which is already public in any appearance before congress.

In addition, access to our underlying work product is being decided in a process that does not involve our office. So beyond what I have said here today, and what is contained in our written work, I do not believe it is appropriate for me to speak further about the investigation or to comment on the actions of the Justice Department or Congress. And it’s for that reason I will not be taking questions today as well.

Now before I step away, I want to thank the attorneys, the FBI agents, and analysts, the professional staff who helped us conduct this investigation in a fair and independent manner. These individuals who spent nearly two years with the Special Counsel’s Office were of the highest integrity.

And I will close by reiterating the central allegation of our indictments — that there were multiple, systematic efforts to interference in our election. That allegation deserves the attention of every American.
