The Los Angeles Police Department said it would open an inquiry into how a recruitment ad for its department had appeared on the website for Breitbart, saying that it created “a negative juxtaposition to our core values.”

A screenshot of the ad circulated on Twitter. It showed a female police officer in uniform and read, “Choose your future. LAPD is hiring!”

The placement sparked complaints that the department was advertising on Breitbart News Network, better known just as Breitbart, a right-wing opinion and news website.

“The LAPD celebrates diversity and embraces it within our ranks, and within the city we serve,” the department said on Twitter on Saturday. “We are aware that a recruitment advertisement has been circulated on a website that creates a negative juxtaposition to our core values.”
