“Charging the president with a crime was ... not an option we could consider,” Mueller told reporters as he announced his resignation. “We concluded that we would not reach a determination one way or the other about whether the president committed a crime.” In his first public comments in the probe, Mueller said on Wednesday "it would be unfair" to potentially accuse someone of a crime when the person couldn't stand trial to defend himself.

His comments echoed the findings in his public report.

Mueller's report revealed that President Donald Trump tried to seize control of the Russia probe and force Mueller's removal to stop him from investigating potential obstruction of justice by the Republican president.

He said he's leaving the Justice Department now that he's concluded his Russia investigation.

Mueller made the announcement Wednesday in his first public statement since his appointment two years ago.
