Durham's prosecutorial record paled in comparison with Mueller's investigation of suspicions that the 2016 Trump presidential campaign courted Russian assistance.

Mueller did not find "collusion," but his report presented compelling evidence that Russian entities helped Trump's 2016 campaign. And it detailed and documented ways the Trump White House subsequently worked to obstruct the Mueller probe.

Mueller charged more than two dozen people, although many were foreigners who have not been brought to justice. He also landed a guilty plea from Trump's first national security adviser, Mike Flynn, now a Southwest Florida resident, and the conviction of Trump political confidant Roger Stone, who lives in South Florida. Trump ultimately pardoned both men for their crimes.

Accepting pardon means admission of guilt
