The editor of The Miami Herald’s Spanish-language publication resigns.

A top editor of The Miami Herald’s Spanish-language sister publication, El Nuevo Herald, has resigned and its publisher has been demoted after a racist and anti-Semitic column was published in a paid insert inside the newspaper this month.

Kristin Roberts, vice president of news at McClatchy, which publishes The Herald and El Nuevo Herald, announced the leadership shake-up on Thursday in an email to staff, which The New York Times obtained.

Ms. Roberts said Nancy San Martin, El Nuevo Herald’s managing editor, had resigned.

Aminda Marques Gonzalez, the executive editor and publisher of The Herald and El Nuevo Herald, will no longer be publisher, a job she had held since April 2019, but will remain executive editor.

The column was published on Sept. 11 in Libre, a Friday supplement in El Nuevo Herald. The author, Roberto Luque-Escalona, took aim at American Jews who support Black Lives Matter.

“What kind of people are these Jews?” Mr. Luque-Escalona wrote. “They are always talking about the Holocaust, but have they now forgotten Kristallnacht, when Nazi thugs razed Jewish businesses throughout Germany? The same is being done by B.L.M. and Antifa, only the Nazis did not rob; they only destroyed.”

Ms. San Martin and Ms. Marques apologized to readers several days after the column was published, saying: “The fact that no one in leadership, beginning with us, had previously read this advertising insert until this issue was surfaced by a reader is distressing.”

In a statement last week, McClatchy said an internal review had resulted in a termination of the company’s commercial relationship with Libre.
