The report said that in June 2017, Trump directed White House Counsel Don McGahn to call the acting attorney general and say that Mueller must be ousted because he had conflicts of interest.
McGahn refused - deciding he would rather resign than trigger what he regarded as a potential Saturday Night Massacre of Watergate firings fame.
For all of that, Mueller said in his report that he could not conclusively determine that Trump had committed criminal obstruction of justice.
The Justice Department posted a redacted version of the report online Thursday morning, 90 minutes after Attorney General William Barr offered his own final assessment of the findings.
The two-volume, 448-page report recounts how Trump repeatedly sought to take control of the Russia probe.
The president's lawyers have said Trump's conduct fell within his constitutional powers, but Mueller's team deemed the episodes deserving of criminal scrutiny.
Mueller reported that Trump had been agitated at the special counsel probe from its earliest days, reacting to Mueller's appointment by saying it was the "end of his presidency."
As for the question of whether the Trump campaign had colluded with Russia during the 2016 presidential campaign, Mueller wrote, "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."
Mueller also said there wasn't sufficient evidence to charge any campaign officials with working as an unregistered foreign agent of Russia.
