It didn’t take long for the “Recall Mayor Ed Lee 2016” effort to turn ugly. The small, fringe group filed papers last Tuesday to announce their intention to collect enough signatures to put the recall on a special election ballot.

They followed that up on Friday with a rally of roughly 20 recall supporters on the steps of City Hall. But when they arrived, they were met by a group of some 200 opponents, many of whom were Asian. This week a video from the rally appeared, showing a recall supporter yelling “Go back to China,” and “You take your Chinese asses back where you came from,” to the Lee backers.

Warning: Explicit language is used in the video below:

A press release from a group calling itself SWRC (Stop the Wasteful Recall Coalition) included quotes from State Assemblyman David Chiu saying it was, “shocking and deeply offensive to hear such openly hateful language used against Chinese Americans — and on the steps of San Francisco City Hall of all places.”

The recall effort is opposed by Chinatown power broker Rose Pak, who said, “No elected official is going to support them. And I want them to know that.”

The group will need to collect over 47,000 signatures to get the recall to the ballot. The special election would cost the city some $3.5 million, according to John Arntz, the city’s election chief.
