Special counsel Robert Mueller says President Donald Trump's efforts to influence the Russia investigation "were mostly unsuccessful," but that was because the people surrounding the president "declined to carry out orders to accede to his requests."

AP reporter Chad Day gives an initial review in this AP debrief of the two-volume report that exceeds 400 pages.

"The first volume that deals with Russian election interference and the actions of the Trump campaign is a couple of hundred pages long and goes into exhaustive detail about the information that they've gathered," he says.

"Interviewing 500 witnesses, issuing more than twenty eight hundred subpoenas, and putting together probably the most complete picture of what happened during the 2016 election involving the Trump campaign and Russia."

Mueller's report details instances by several officials, including former FBI Director James Comey, former White House counsel Don McGahn and former campaign manager Corey Lewandowski, ignoring or refusing Trump's requests to interfere in the investigation.

"But some of those episodes show that Trump made several attempts to seize control of the investigation try to have Special Counsel Robert Mueller removed from the probe, or that his attorneys were trying to gather information about what people who were cooperating with the investigation were telling prosecutors," Day says.

"So the headline today is that Mueller has made two big conclusions out of his report. Number one is that he did not establish that there was a criminal conspiracy between the Russian government and the Trump campaign to interfere in the 2016 election. The other is that he did not exonerate the president on the question of whether he obstructed justice, or tried to influence the Russia probe and crossed over into criminal conduct.

"In particular on the question of obstruction, Mueller examined 10 different episodes in which he was looking at the president's conduct to determine whether or not it crossed over into criminal conduct. Some of those episodes show that Trump made several attempts to seize control of the investigation, try to have Special Counsel Robert Mueller removed from the probe, or that his attorneys were trying to gather information about what people who were cooperating with the investigation were telling prosecutors."

"In particular, there's one episode that's related involving his personal attorney of his who is trying to gather information from former National Security Adviser Michael Flynn. Now, this is going back in time a little bit, but Flynn had just cut off contact with the Trump legal team, ahead of his pleading guilty and cooperating with the government. The report says that one of Trump's attorneys then reached out and tried to remind them that the president had warm feelings for Flynn and ask him to see if there was any information that he knew that could implicate the president. Whenever Flynn's attorneys rebuffed that effort, the attorney then said that he would remind the president that that Flynn's actions showed hostility towards the president. So, what they're showing is that they're painting a picture here of a president and people around him who are trying to shape and gather information about the probe but also to in some cases you know take control of it and influence the direction of where it's going."

"The report also details what happened in the months right after Special Counsel Robert Mueller was appointed in May of 2017. In particular, it shows that the president ordered his then White House counsel Don McGhan to try to have a special counsel Robert Mueller removed. Now McGahn rebuffed this effort but it shows how the president and the report quotes him saw the probe as possible end to his presidency, and something that would threaten his power. And at that point was trying to take efforts to take control of the investigation by having Mueller removed."

Redacted report on Russian interference on 2016 presidential election

Attorney General Jeff Sessions was interviewed for hours last week in special counsel Robert Mueller's Russia investigation, the Justice Department confirmed Tuesday. He's the highest-ranking Trump administration official and first Cabinet member known to have submitted to questioning.

The interview came as Mueller investigates whether President Donald Trump's actions in office, including the firing of FBI Director James Comey, constitute efforts to obstruct the FBI probe into contacts between his 2016 campaign and Russia. Trump's own lawyers are discussing the prospect of an interview with the president himself, and White House officials state publicly that they anticipate a resolution soon to the investigation.

The questioning of the country's chief law enforcement officer is a reflection of investigators' continued interest in whether the president took steps to improperly obstruct justice. That question has been at the heart of the investigation for months as agents and prosecutors have questioned multiple current and former White House officials.

Sessions himself is seen as a potentially important witness given his direct involvement in the May 9 firing of Comey. The White House initially said the termination was done on the recommendation of the Justice Department and cited a memo from Deputy Attorney General Rod Rosenstein that faulted Comey for his handling of the Hillary Clinton email server investigation as justification.

But Trump said later that he was thinking of "this Russia thing" when he fired Comey, and he had decided to make the move even before the Justice Department's recommendations.

Sessions was one of Trump's earliest and most loyal allies, the first senator to endorse him during the presidential campaign. They shared an ambitious law-and-order agenda that focuses on hawkish immigration policies and tough-on-crime strategies that engendered affection from many conservatives.

He has continued to push Trump's agenda on everything from gangs and the opioid crisis to religious freedom, giving the president credit every step of the way.

But his decision to step aside from the Russia investigation has strained their bond, and the two men now rarely speak directly. Trump saw the recusal as weak and disloyal, believing his attorney general should be doing more to protect him

Over the past several months Mueller investigators have spoken with other key people close to the president, including White House Counsel Don McGahn, former chief of staff Reince Priebus and Trump's son-in-law, Jared Kushner.

Mueller has conveyed interest in speaking with the president, and White House attorney Ty Cobb said that is "under active discussion" with Trump's individual lawyers. He said last week on a CBS News' political podcast, "The Takeout," that he expected the investigation to be wrapped up within weeks.

Sessions recused himself from the Russia investigation in early March after acknowledging that he had had two previously undisclosed encounters with the Russian ambassador during Trump's 2016 presidential campaign. He said at the time that it would be improper for him to oversee a probe into a campaign for which he was a vocal and prominent supporter.

Since then, Trump has lashed out repeatedly on Twitter at Sessions and the Justice Department.

People familiar with the matter have told The Associated Press that McGahn had contacted Sessions to urge him to retain control of the investigation. McGahn was acting at the behest of the president, according to one of those people, who spoke only on condition of anonymity because the person was not authorized to speak publicly by name.

Rosenstein appointed Mueller, a former FBI director, to take over the Russia investigation one week after Comey was fired. He oversees the work of Mueller's investigators, but he told the AP in an interview last June that he, too, would recuse himself if his actions ever became relevant to the probe.

Sessions' attorney, Chuck Cooper, declined to comment, as did the White House.

Four people have so far been charged in the Mueller investigation, including former White House National Security Adviser Michael Flynn and former Trump campaign chairman Paul Manafort. Flynn and George Papadopoulos, a former campaign foreign policy adviser, have pleaded guilty to lying to the FBI.

Sessions' interview with the Mueller team was first reported by The New York Times.

"What he actually most critically is involved in was the firing of FBI Director Jim Comey back in May, and that is one of the critical episodes of the Trump presidency that's been under investigation by Bob Mueller. And it's part of a series of questions as to whether the president took actions while in office to stymie the FBI investigation into contacts between his campaign and Russia. And you'll remember that Jeff Sessions was very important to that because he is somebody who endorsed the firing of Director Comey."
