But it's unlikely that the full Mueller report or the public testimony will untangle the dilemma that Democrats face.
He left out a previous sentence that would have been far more damaging to Trump: "The evidence we obtained about the president's actions and intent presents hard issues that prevent us from conclusively determining that no criminal conduct occurred".
The Kremlin says the Mueller report has not presented any evidence that it meddled in U.S. elections, and President Donald Trump claimed vindication after the release of the long-awaited redacted document.
Mueller also wrote in his report, "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".
Half a dozen former Trump aides were charged by Mr Mueller's office or convicted of crimes during the 22-month-long investigation.
Attorney general or advocate for White House? While it outlines an extensive campaign of Russian interference to help Mr. Trump win - and connections between his circle and Moscow - it concludes that the President's campaign did not collude. Barr has already pledged to give a version of the report where the only redactions will be grand jury info, which is illegal to share, but Nadler is still issuing the subpoena. "He said he didn't meddle".
Trump did not want to let this go, even though he was told repeatedly - even by Steve Bannon, a man whose absence of morality rivals Trump's own - that Sessions simply couldn't do Trump's dirty work in this case. "But if you try multiple times to shut an investigation down, how is that not obstruction?"
But none of these contacts, Mr. Mueller found, provided evidence that the Trump campaign and the Russians were working together.
The president's lawyers have said Trump's conduct fell within his constitutional powers, but Mueller's team deemed the episodes deserving of scrutiny for potential criminal acts. "I don't see any reason why it would be".
Within minutes of the issuance of the slightly redacted document, congressional Democrats were claiming confirmation of their charges of Trump's collaboration with Russian Federation, while the White House and Fox News were hailing the president's complete vindication.
Some former officials worry nonetheless that without a more forceful US response, Russian Federation or other adversaries will seek to get away with such behavior again. He covers USA politics and current affairs.
But if they do, it will not be in a US court of law.
Trump and key members of his team have been repeatedly rejecting all the accusations concerning any collusion between the Trump campaign and Russian Federation.
Fire experts say the air water tankers President Trump suggested be used to douse the Notre Dame cathedral fire would have collapsed the 850-year-old structure. "We're certainly not seeing the counterintelligence investigation".
"I'm hoping that people will get in trouble and get indicted over this whole thing", says Walter Smith, who is retired and lives near Russellville. Jake Tapper at CNN reported that when visiting border agents in Calexico, California, Trump told them simply to deny entry to asylum seekers and then to disobey judges who might try to compel them to follow the law.
Hints of that type of information, which could reveal sources or methods, or harm ongoing intelligence operations, may be contained in parts of the report that have been redacted. Just "no collusion", he said, and the Trump campaign thunderously agreed.
Sanders called for efforts to prevent future foreign interference in elections. "As far as I can tell, they wanted so badly for collusion to be true, for the downfall of American democracy and failure of the Trump presidency, that they would say and do anything to make it true".
USA media outlets and numerous "high-profile" individuals were also taken in by the IRA.
"Statements are made about me by certain people in the Crazy Mueller Report, in itself written by 18 Angry Democrat Trump Haters, which are fabricated & totally untrue".

"I am open to working with the Department to reach a reasonable accommodation for access to these materials, however I can not accept any proposal which leaves most of Congress in the dark, as they grapple with their duties of legislation, oversight and constitutional accountability", Nadler said in a statement. "We have to hear from Mueller and ask him a lot of questions", Nadler said Friday.
"The obstruction stuff is pretty damning", added former Trump campaign adviser Sam Nunberg.
