The report cites unnamed former law enforcement officials and others familiar with the investigation.
The criminal and counterintelligence elements were coupled together into one investigation, former law enforcement officials said in interviews in recent weeks, because if Trump had ousted the head of the FBI to impede or even end the Russian Federation investigation, that was both a possible crime and a national security concern.
Lawyers for U.S. President Donald Trump have told special counsel Robert Mueller that he will not answer any more questions in the probe of Russia's meddling in the 2016 election, Trump lawyer Rudy Giuliani told Reuters on Wednesday.
Rudolph Giuliani, one of Trump's attorneys, also downplayed the significance of the investigation.
The Times says it's unclear whether Mueller is still pursuing it.
In a phone interview Giuliani, who is a member of Trump's legal team, told the news outlet that the team should be able to check the conclusions of the report, which is now in its 20th month. And this is the investigation they opened after Comey was sacked. The smart bet would be that the phrase "witch hunt" and the caps-lock button would be involved.
The president's ties to Russian Federation during the 2016 campaign had aroused suspicions among agents and senior Federal Bureau of Investigation officials, who were unsure how to proceed with such a sensitive inquiry and thus chose to hesitate.
The Washington Post reported Wednesday that White House counsel Pat Cipollone is gearing up by hiring 17 new lawyers to the team to prepare to "prevent President Trump's confidential discussions with top advisers from being disclosed to House Democratic investigators and revealed in the special counsel's long-awaited report".
Presidents Donald Trump and Vladimir Putin shake hands.
The investigation has not concluded and the public has not been notified of the final results. Trump also plays a central role in a separate case in NY, where prosecutors have implicated him in a crime.
Neal Katyal, the former acting solicitor general under President Obama, wrote that any Trump attempts to hide parts of the report from the public would be defeated in court.
