As a lifelong Republican, I am proud that my party has consistently revered the rule of law as a central tenet of our country’s values. I have been honored to serve under seven presidents, including as U.S. attorney general  under Presidents Ronald Reagan and George H.W. Bush. I know from experience that the Justice Department effectively performs the awesome responsibility of enforcing our laws and assuring that justice is provided equally and fairly to all.
Many recent comments  about special counsel Robert S. Mueller III and his investigation have been regrettable and undeserved. I was surprised to see President Trump’s lawyer, Rudolph W. Giuliani, a respected former U.S. attorney, suggest  this week that Mueller is “trying very, very hard to frame” the president, echoing comments made by the president himself that the investigation is “a Witch Hunt .” Those comments are the antithesis of who Mueller is and how he operates.
I know Bob Mueller as a colleague in law enforcement and as a friend, and I highly respect his judgment and moral compass. Mueller is the right person to investigate Russia’s apparent assault  on our democracy. He possesses the skills and discipline necessary to perform his role, and his past leadership as head of the Justice Department’s criminal division and as director of the FBI  leave no doubt as to his ability to evenhandedly conduct significant investigations. He is serious but not sensational and loyal to the rule of law.
