OAKLAND — Social media has lambasted Mayor Libby Schaaf over a picture she posted of her with some young people taking part in her annual summer internship program, with those commenting saying none are black.

“Not one single black face, and here folks is the optical narrative of how black people are being disappeared in Oakland,” said activist and 2018 mayoral candidate Cat Brooks via Twitter.

“I wish your summer interns well but must wonder why in the City of Oakland that has a large population of African Americans, not one of your interns is African American? I am shocked. Shocked. And actually angry,” tweeted user Malla Hadley.

However, one of the interns in the photo, 20-year-old Oakland-native Jazz Broughton, is in fact African-American, she told the Bay Area News Group.

Schaaf took to Twitter on Thursday to apologize for “the impact” that the photo caused.

“I posted a photo to celebrate our new intern cohort and not everyone from my city saw themselves in it. That caused pain, and at a moment when our African-American residents see and feel less representation in our town,” Schaaf said via Twitter.

Brooks, in an interview with the Bay Area News Group, said the post was tone-deaf, and a “symptom of a much larger disease” that black people feel less represented in Oakland.

“This was just one more kick in the gut to black Oakland,” Brooks said.

Brooks stressed that she doesn’t put any of the blame on the interns themselves.

Schaaf said her office, “like our city, embraces diversity, strives for inclusion and is open to everyone.”

More participants will join the program throughout the summer. Schaaf encouraged students to apply, especially those “from under-represented communities.” Applicants can email a cover letter and resume to mayorsofficeintern@gmail.com.

Broughton, who is studying International Affairs and African-American studies at UC Los Angeles, said she doesn’t take the outrage over Schaaf’s post personally. She doesn’t think the picture “does justice to the diversity” among the program’s participants, she said, many of whom identify as people of color.
