Martinez has resigned after making a series of disturbing racist remarks in a leaked audio recording, while Herrera - also on tape - has additionally stood down as President of the Los Angeles County Federation of Labor.

The conversation from October 2021 was posted anonymously on Reddit, and featured Martinez and councilmember Kevin de León using racist and derogatory language.

Martinez has resigned and issued a public apology following outrage from other City Council leaders, while de León has apologised.

Herrera and councilmember Gil Cedillo also faced criticism for featuring in the recording.

Herrera had his resignation as President of the Los Angeles County Federation of Labor accepted and is believed to also be resigning from the Organising Committee for the 2028 Olympics and Paralympics.

In the leaked audio, Martinez is heard using a Spanish racial slur to refer to the black son of councillor Mike Bonin during a conversation on redrawing Council district boundaries.

In a family statement attributed to Bonin and his partner Sean Arian, they said: "We are appalled, angry and absolutely disgusted that Nury Martinez attacked our son with horrific racist slurs, and talked about her desire to physically harm him.

"It's vile, abhorrent, and utterly disgraceful."

Bonin had called on Martinez, de León and Herrera to resign from office, and criticised Cedillo for his "tacit acceptance" of the remarks in the conversation.

In resigning as President of the Council, Martinez offered an apology to Bonin.

"I take responsibility for what I said and there are no excuses for those comments," she said.

"I'm so sorry.

"I sincerely apologize to the people I hurt with my words: to my colleagues, their families, especially to Mike, Sean, and your son."

De León said: "There were comments made in the context of this meeting that are wholly inappropriate; and I regret appearing to condone and even contribute to certain insensitive comments made about a colleague and his family in private."

Cedillo has also apologised and admitted "I should have intervened".

Los Angeles Mayor Eric Garcetti said he was "saddened by what I read".

The Play Equity Fund, established by the LA84 Foundation which was formed by the Organising Committee from when the city last held the Olympics, joined the criticism of the officials in the recording, describing it as a "shameful and divisive conversation".

"There is no place in our city for such hateful and racist comments," a statement read.

"The Play Equity Fund is a legacy of the 1984 Summer Olympics, an event that took place when the world was deeply divided and showed on an international stage what a community united with a common purpose looks like.

"Today is no different, we choose to stand together with all communities who are working to bridge divides and improve the lives of every Angelino with love, kindness, respect, and dignity for all.

"Today we reaffirm our commitment to the ideals of the Olympic movement and our commitment to advance equity through sport and play, to combat racism in all its forms and to build a better world through sport."

Martinez, De León and Cedillo remain on the Council, but are facing growing pressure over their positions.
