"If we had confidence the President did not commit a crime, we would have said so."

From the Executive Summary: "Although the investigation established that the Russian government perceived it would benefit from a Trump presidency and worked to secure that outcome, and that the Campaign expected it would benefit electorally from information stolen and released through Russian efforts, the investigation did not establish that members of the Trump Campaign conspired or coordinated with the Russian government in its election interference activities."

It is a lie to suggest that there was "no evidence"; Mueller himself in a public statement literally said there was merely "insufficient evidence" to rise to the bar of conspiracy, contradicting your quote.
