Ron Conway, a tech billionaire and a Major Supporter of the San Francisco DA Recall, is one of the big backers of the effort against Oakland Mayor Sheng Tao. Petitioners have said that they have collected over 13,000 signatures. They need 24,638. 

The big issue has been crime. Tao has fired the Oakland Police Chief and rejected three possible replacements proposed by a committee. One of the leaders of the recall effort is Alameda County Judge Brenda Harbin-Forte, who served on the Police Commission and was removed by Tao.
