One day in the summer of 1969, a young Marine lieutenant named Bob Mueller arrived in Hawaii for a rendezvous with his wife, Ann. She was flying in from the East Coast with the couple’s infant daughter, Cynthia, a child Mueller had never met. Mueller had taken a plane from Vietnam.

After nine months at war, he was finally due for a few short days of R&R outside the battle zone. Mueller had seen intense combat since he last said goodbye to his wife. He’d received the Bronze Star with a distinction for valor for his actions in one battle, and he’d been airlifted out of the jungle during another firefight after being shot in the thigh. He and Ann had spoken only twice since he’d left for South Vietnam.

Despite all that, Mueller confessed to her in Hawaii that he was thinking of extending his deployment for another six months, and maybe even making a career in the Marines.

Ann was understandably ill at ease about the prospect. But as it turned out, she wouldn’t be a Marine wife for much longer. It was standard practice for Marines to be rotated out of combat, and later that year Mueller found himself assigned to a desk job at Marine headquarters in Arlington, Virginia. There he discovered something about himself: “I didn’t relish the US Marine Corps absent combat.”

So he headed to law school with the goal of serving his country as a prosecutor. He went on to hold high positions in five presidential administrations. He led the Criminal Division of the Justice Department, overseeing the US investigation of the Lockerbie bombing and the federal prosecution of the Gambino crime family boss John Gotti. He became director of the FBI one week before September 11, 2001, and stayed on to become the bureau’s longest-serving director since J. Edgar Hoover.

And yet, throughout his five-decade career, that year of combat experience with the Marines has loomed large in Mueller’s mind. “I’m most proud the Marines Corps deemed me worthy of leading other Marines,” he told me in a 2009 interview.

Today, the face-off between Special Counsel Robert Mueller and President Donald Trump stands out, amid the black comedy of Trump’s Washington, as an epic tale of diverging American elites: a story of two men—born just two years apart, raised in similar wealthy backgrounds in Northeastern cities, both deeply influenced by their fathers, both star prep school athletes, both Ivy League educated—who now find themselves playing very different roles in a riveting national drama about political corruption and Russia’s interference in the 2016 election. The two men have lived their lives in pursuit of almost diametrically opposed goals—Mueller a life of patrician public service, Trump a life of private profit.

Those divergent paths began with Vietnam, the conflict that tore the country apart just as both men graduated from college in the 1960s. Despite having been educated at an elite private military academy, Donald Trump famously drew five draft deferments, including one for bone spurs in his feet. He would later joke, repeatedly, that his success at avoiding sexually transmitted diseases while dating numerous women in the 1980s was “my personal Vietnam. I feel like a great and very brave soldier.”

Mueller, for his part, not only volunteered for the Marines, he spent a year waiting for an injured knee to heal so he could serve. And he has said ­little about his time in Vietnam over the years. When he was leading the FBI through the catastrophe of 9/11 and its aftermath, he would brush off the crushing stress, saying, “I’m getting a lot more sleep now than I ever did in Vietnam.” One of the only other times his staff at the FBI ever heard him mention his Marine service was on a flight home from an official international trip. They were watching We Were Soldiers, a 2002 film starring Mel Gibson about some of the early battles in Vietnam. Mueller glanced at the screen and observed, “Pretty accurate.”
