‘Devastating’: Internet reacts as Mueller blows a massive hole in GOP’s ‘no obstruction’ claims
Robert Mueller testifies before Congress (screengrab)

Special counsel Robert Mueller delivered his first public remarks about his investigation of President Donald Trump's campaign ties to Russia -- and he clearly cast doubt on the president's "no collusion" defense.

Mueller announced that he was closing his office and resigning, and said his "largely public" report must be allowed to speak for itself.

But he made clear his office never considered charging the president because Department of Justice regulations would not allow that, but he also made clear evidence showed Trump obstructed justice during the investigation.
