FILE - In this June 1, 2020, file photo, San Francisco Mayor London Breed speaks outside City Hall in San Francisco.
Breed joined a chorus of officials who have denounced the tweets by the vice president of San Francisco's school board, Alison Collins, as racist and anti-Asian.
The posts resurfaced last week amid a surge of violence and harassment against Asian Americans in the San Francisco Bay Area and around the country.
They are the latest embarrassment for San Franciscoโs school board, which has prided itself on putting racial equity at the top of its agenda.
Under a plan recently negotiated with its labor unions, San Francisco plans to phase-in the reopening of elementary school classrooms in mid-April.
