Washington (AP) -Special counsel Robert Mueller's report says President Donald Trump reacted to his appointment by saying it was the "end of his presidency."

Mueller investigated multiple instances of Trump attempting to curtail the special counsel probe as part of determining whether the president committed obstruction of justice.

A redacted version of Mueller's report was released Thursday morning by Attorney General William Barr.

Meanwhile, Trump's lawyer is defending him after the special counsel's report said Trump tried to seize control of the Russia investigation.

Rudy Giuliani, speaking to Fox News, said Trump "did not have a guilty motive."

The incidents scrutinized by Mueller's team include Trump's firing of FBI Director James Comey, the president's directive to subordinates to have Mueller fired and efforts to encourage witnesses not to cooperate.

Giuliani did not dispute the facts of those incidents, but said Trump was an innocent man reacting normally in the face of what he said was a heavily biased investigation. The former New York City mayor said the efforts were "an attempt not to get framed."

Mueller found that contacts between Russian Ambassador Sergei Kislyak and Trump campaign officials in April 2016 and at the 2016 GOP convention were "brief, public, and non-substantive."

Mueller's assessment came as part of his investigation into potential collusion between the Trump campaign and Russia.

Mueller's report adds that his office "did not establish" that efforts to alter the GOP platform's language on Ukraine at the convention were done at the behest of Trump or Russia.

Additionally, Mueller did not establish that a conversation between Kislyak and then-Alabama Sen. Jeff Sessions in September 2016 included "any more than a passing mention of the presidential campaign." Sessions later served as Trump's attorney general.
