Have you been missing Campbell Brown? There was a long period when she stepped forth to position herself as the symbol of the corporate reform movement, warning the world to be wary of public schools loaded with pedophile teachers who were protected by unions and tenure. As Michelle Rhee faded away, Campbell Brown’s star rose in the corporate reform firmament.

Her Partnership for Educational Justice launched lawsuits against tenure, none of which have been successful. She garnered millions from the usual billionaires to start a news site called The 74 Million, to sing the praises of charter schools and privatization.  She served on the board of Betsy DeVos’s American Federation for Children, which handed out millions of dollars to fund candidates who support charters and vouchers. Betsy, in turn, funded The 74 Million.

But now she has left us! She has joined the messaging team at Facebook, where she is smoothing ruffled feathers and soothing angry critics. In this long profile in the New York Times, Campbell’s role as the dragon slayer of public schools gets only a few paragraphs.

Here is what the New York Times says about Campbell’s foray into education as the new Michelle Rhee:

But after leaving CNN, Ms. Brown did shed her journalistic skin, and turned herself into a political animal.

“Ms. Brown became an activist focused on education. She fought teachers’ unions, a tactic some friends think was meant to position her for a run for office. A New York Magazine profile once posed the question, “How did an ex-news anchor become the most controversial woman in school reform?”

“She was a celebrity in ed reform,” said Eva Moskowitz, the founder and chief executive of the Success Academy Charter Schools, where Ms. Brown is a board member. “We just didn’t have people of her prominence before.”

“Ms. Brown also started an education news site called The 74 Million, which often reports on issues around teachers’ unions, and an advocacy group called The Partnership for Educational Justice, which funded a lawsuit against teacher tenure. She served on the board of Betsy DeVos’s American Federation for Children. (Ms. Devos has funded The 74 Million.) When President Trump nominated Ms. DeVos to be Secretary of Education last year, Ms. Brown wrote an op-ed in her defense, calling Ms. DeVos a “friend.”

“By then, Facebook was in crisis mode over how it handled news.”

Her career as the nation’s leader in the fight to crush teachers, unions, and public schools has receded into the background, perhaps ended.

Who will be the new face of corporate reform? Who will be the next bold reformer to grace the cover of TIME magazine, broom in hand, as Rhee once did?

Campbell Brown, we hardly knew ye.
