Like Trump, whom he interviewed twice and treats with kid gloves, Gerth falsely suggests that Special Counsel Robert Mueller somehow exculpated the former president. In fact, Mueller showed that Trump repeatedly obstructed justice to stymie the Russia investigation. And the special counsel indicated that Trump's "dangling" of pardons to key witnesses like Paul Manafort and Roger Stone — who ultimately were pardoned — had cut off crucial avenues of investigation and testimony. Mueller cited 10 instances of obstruction of justice he could not prosecute because of the policy not to indict a sitting president for criminal activity. Here, Gerth is perpetuating the coverup.

Beyond any specific problems in Gerth's deeply defective work, however, is the question of why the magazine made such an odd choice to fulfill this sensitive task. During his years at the Times, he gained notoriety for two major stories that looked impressive when first published — and then fell spectacularly flat.

In 1992, he wrote a front-page article on Bill and Hillary Clinton's investment in an ill-fated real estate deal known as "Whitewater," which spawned endless news coverage, congressional investigations and a special counsel probe mismanaged by Ken Starr that cost nearly $70 million. The erroneous headline on Gerth's story— "CLINTONS JOINED S & L OPERATOR IN AN OZARK REAL ESTATE VENTURE" — was only the first of many regrettable errors. Multiple investigations failed to confirm Gerth's insinuations of wrongdoing by the Clintons.

In 1999, Gerth and a fellow Times reporter published another bombshell, headlined "BREACH AT LOS ALAMOS: China Stole Nuclear Secrets For Bombs, U.S. Aides Say." The article pointed a finger of suspicion at a Taiwanese American scientist named Wen Ho Lee, who was subsequently indicted and imprisoned — until he was released for lack of sufficient evidence to convict him of espionage. He ultimately pled guilty to a minor offense and received an apology from President Clinton. (The Times felt obliged to publish a note critiquing its own handling of the story after Lee's prosecution failed.)

What brings those episodes to mind is that in both instances, Gerth appeared to be heavily influenced by partisan figures on the Right with agendas that obscured the truth. His chief Whitewater sources were Sheffield Nelson, an embittered Republican businessman who had run against Clinton for governor two years earlier, and Clinton's former Whitewater partner James McDougal, who was both dishonest and mentally ill. His principal source on Wen Ho Lee appears to have been an Energy Department security official named Notra Trulock III, a right-wing conspiracy theorist who was credibly accused by his colleagues of ethnic bias against Lee.

Gerth's skewed reporting on Whitewater and Wen Ho Lee came under harsh criticism from other journalists. But the assessment that may now sting the most appeared in the Columbia Journalism Review months after the Lee prosecution had fizzled.

Writing about the Times' "painful" self-scrutiny, Michael Hoyt, who became the magazine's editor, called the Lee story "hard to read... without thinking that readers were supposed to believe — from the way the facts were marshaled and supported by inferences and quotes — that Wen Ho Lee was a probable spy and that those in the government who doubted it were politically motivated." The paper's editors, wrote Hoyt, should have taken "a closer look" at Gerth's main source as well as the political motivations of congressional Republicans pushing it, and "should have investigated hints early on that the legal case against Lee was not all that impressive."

Gerth's latest misadventure, providing tilted alibis for Trump, follows a pattern of decades. It should surprise nobody, especially his now-infuriated former colleagues at the Times. Hailed by the right-wing media, he appears to believe that he is in a position to lecture his fellow journalists. They would do better taking instruction elsewhere.
