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

An FBI agent whose anti-Trump text messages fueled suspicions of partisan bias told lawmakers Thursday that his work has never been tainted by politics and that the intense scrutiny he is facing represents "just another victory notch in Putin's belt."

Peter Strzok, who helped lead FBI investigations into Hillary Clinton's email use and potential coordination between Russia and Donald Trump's campaign, was testifying publicly for the first time since being removed from special counsel Robert Mueller's team following the discovery of the derogatory text messages last year.

In his opening statement, Strzok said he has never allowed personal opinions to infect his work, that he knew information during the campaign that had the potential to damage Trump but never contemplated leaking it and that the focus on him by Congress is misguided and plays into "our enemies' campaign to tear America apart."

Republican members of the House judiciary and oversight committees were expected to grill Strzok for hours as they argue that the text messages with FBI lawyer Lisa Page color the outcome of the Clinton email investigation and undercut the FBI's ongoing investigation into Russian election interference.

"We don't want to read text message after text message dripping with bias against one of the two presidential candidates. We don't enjoy finding compelling evidence that the FBI director had predetermined the outcome of the case months in advance. But that is thus far what we have found."

2. Wide of hearing

3. SOUNDBITE (English) Rep. Trey Gowdy, (R) South Carolina, House Oversight Committee Chairman:

"We learned that Agent Strzok has a most unusual and largely self-serving definition of bias. Agent Strzok, despite the plain language of his text and emails, despite the inspector general's report and despite common sense, doesn't think he was biased. He thinks calling someone 'destabilizing for the country' isn't bias. He thinks promising to protect the country from someone he hasn't even begun to investigate isn't bias."

"Strzok even talked about impeachment the day special counsel was appointed. That is prejudging guilt, it is prejudging punishment and it is textbook bias."
