Below are the 10 most important takeaways gleaned from Robert Mueller's testimony before the House Judiciary and Intelligence Committees on Wednesday.

Mueller said all he wanted to say in his report

When Mueller finally agreed to testify before Congress - after more than two years of silence about the Russia investigation - the special counsel said he 'would not provide information beyond that which is already public' in the report published in April.

He stuck to that promise throughout Wednesday's hearing, declining or deferring nearly 200 questions from committee members.

Mueller's reasons for not answering included not wanting to speculate, being unable to detail internal Justice Department deliberations and being under orders not to broach specific topics.

Trump was paying attention

After saying that he couldn't be bothered to watch Mueller's testimony, President Trump made it clear that he was tuned in as he tweeted multiple reactions to the proceedings on Wednesday.

'I'm not going to be watching Mueller because you can't take all those bites out of the apple,' Trump told reporters in the Oval Office on Monday. 'We had no collusion, no obstruction.'

Before the hearing even kicked off Trump had posted seven tweets about the hearing, echoing his go-to attacks on 'Mueller & his band of 18 Angry Democrats'.

Over the next eight hours tweeted and retweeted 14 posts about Mueller's testimony, including multiple videos of Republican lawmakers grilling the special counsel.

'TRUTH IS A FORCE OF NATURE!' he declared just after 2.30pm.

Mueller didn't subpoena Trump to avoid a lengthy court battle

The special counsel addressed why Trump wasn't interviewed during the two-year-long investigation when New York Democratic Rep Sean Maloney asked him: 'Why didn't you subpoena the president?'

Trump's legal team had refused to have him be interviewed in the probe because they felt such a meeting would amount to a 'perjury trap'.

Before Congress Mueller stated that his team had 'little success' when pushing for an interview for over a year and decided that they didn't want to delay the investigation with a lengthy court battle.

'We did not want to exercise the subpoena power because of the necessity of expediting the end of the investigation,' he said, adding that no one at the Justice Department pressured him to finish the probe.

Mueller acknowledged that Trump's written answers to questions about possible conspiracy with Russia were 'not as useful as the interview would be'.

Trump was not exonerated by the Russia investigation

Judiciary Committee Chairman Jerry Nadler, a New York Democrat, kicked off Wednesday's proceedings by asking Mueller directly if the Russia investigation exonerated President Trump.

'No,' Mueller stated without hesitation.

That goes against the president's repeated claims that the probe proved there was 'no obstruction, no collusion'.

Mueller's team never determined whether Trump committed a crime

While the majority of his answers were straightforward and technical, Mueller struggled when questioned about why he did not indict the president.

During an exchanged with California Democratic Rep Ted Lieu, Mueller stated that the reason he did not even consider indicting Trump on obstruction charges was because of guidance from the DOJ's Office of Legal Counsel that a sitting president cannot be indicted.

That goes against assertions by Attorney General William Barr, who has repeatedly said the OLC's opinion was not the only reason Mueller did not indict Trump.

Arizona Republican Rep Debbie Lesko asked Mueller to clarify that contradiction, at which point he said he 'would have to look closer at it'.

He later conceded that he had misspoken when he characterized the OLC's guidance to Lieu.

'We did not reach a determination as to whether the President committed a crime,' he said.

'Based on Justice Department policy and principles of fairness, we decided we would not make a determination as to whether the president committed a crime.'

Mueller was much less steady than in previous hearings

At times, Mueller, 74, stumbled during answers, asking fast-talking lawmakers to repeat page citations and repeat their questions. He sometimes had to scan the hearing room to locate questioners.

Although his stock answer was to say issues were beyond the purview of his mandate, he also appeared not to recall specific information at times.

'Where are you reading from?' he asked one member, Rep. James Sensenbrenner. 'I am reading from my question,' the Wisconsin Republican lawmaker told him.

Under questioning by Republican Rep Steve Chabot, Mueller didn't show immediate familiarity with political intelligence firm Fusion GPS, a key player in the trail of the Steele Dossier, and a fixture of attention of President Trump and GOP critics of the Mueller probe.

Viewers reacting on social media called out Mueller's unsteadiness early on, remarking that he was acting 'like a confused old man'.

Some said the wobbly performance could be a delaying tactic on the part of the special counsel to frustrate Republican committee members determined to discredit findings that are damaging to Trump.

Mueller and Trump have opposing accounts of what led up to special counsel appointment

Republicans probed Mueller's professional links with Trump in an attempt to show he may have had a reason to be biased against the president - specifically questioning whether he was turned down for the FBI director position the day before being tapped to lead the Russia investigation.

Trump gave his version of events on Wednesday morning, tweeting: 'It has been reported that Robert Mueller is saying that he did not apply and interview for the job of FBI Director (and get turned down) the day before he was wrongfully appointed Special Counsel.

'Hope he doesn't say that under oath in that we have numerous witnesses to the interview, including the Vice President of the United States!'

Mueller contradicted Trump's account when Texas Republican Rep Louie Gohmert seized on his alleged conflicts of interest.

Gohmert asked Mueller about a meeting he had with Trump the day before the special counsel appointment and contended that it was a job interview for the FBI director slot.

Mueller stated that he was not interviewed 'as a candidate' for the position.

Mueller fiercely defended his team's impartiality

The special counsel was calm and composed throughout the proceedings, save for one moment when Florida Republican Rep Greg Steube decried the political affiliations of the lawyers on his team.

Mueller said never in his 25 years in his position had he felt the need to ask the people he works with about their political affiliation.

Rep Gohmert also called Mueller's hiring practices into question, particularly his appointment of FBI agent Peter Strzok - who was later removed from the probe after he was found to have sent anti-Trump text messages to a woman he was involved with.

Mueller said he did not know of Strzok's disdain for Trump before the probe started and learned about it in the summer of 2017, several months into the investigation.

Republicans tried to collect evidence for a probe into Mueller's investigation

Republicans committee members tried both the blast the origins of the Russia probe and potentially establish a record that might play out in an ongoing investigation overseen by Attorney General William Barr.

'Before you arrested [Trump campaign foreign policy aide] George Papadopoulos in July of 2017, he was given $10,000 in ash in Israel. Do you know who gave him that cash?' California Rep Devin Nunes asked Mueller.

'Again, that’s outside our … questions such as that should go to the FBI or the department,' said Mueller.

'But it involved your investigation,’ said Nunes.

‘It involved persons involved in my investigation,’ said Mueller.

Trump lawyer Jay Sekulow released a statement saying: 'This morning’s testimony exposed the troubling deficiencies of the Special Counsel’s investigation. The testimony revealed that this probe was conducted by a small group of politically-biased prosecutors who, as hard as they tried, were unable to establish either obstruction, conspiracy, or collusion between the Trump campaign and Russia. It is also clear that the Special Counsel conducted his two-year investigation unimpeded. The American people understand that this issue is over. They also understand that the case is closed.'

Democrats tried to breathe life into a dense, technical report

The Democrats, who hold a majority on both committees, made a concerted effort to present the investigation's findings in a more provocative and damning light than they had been in the dense, 337-page report.

'Your investigation determined that the Trump campaign -- including Trump himself -- knew that a foreign power was intervening in our election and welcomed it, built Russian meddling into their strategy, and used it,' California Rep Adam Schiff, the House Intelligence Committee chair, said when the afternoon portion began.

'Disloyalty to country. Those are strong words, but how else are we to describe a presidential campaign which did not inform the authorities of a foreign offer of dirt on their opponent, which did not publicly shun it, or turn it away, but which instead invited it, encouraged it, and made full use of it?' Schiff continued.

'That disloyalty may not have been criminal. Constrained by uncooperative witnesses, the destruction of documents and the use of encrypted communications, your team was not able to establish each of the elements of the crime of conspiracy beyond a reasonable doubt, so not a provable crime, in any event', he added.

However, a levelheaded Mueller didn't play along, making for a rather mundane hearing.
