On Thursday supervisor and San Francisco mayoral candidate Jane Kim made public a series of written questions posed to her by a Chronicle reporter after several attempts to reach the candidate by phone had failed. After they were answered, the reporter and her editor concluded that they had asked questions based on incorrect information and, as a result, no story was written. However, those written questions were inappropriately worded and insufficiently researched. They failed to meet the journalistic standards of The Chronicle.

We strive to try to avoid bias in our reporting as well as the appearance of bias, and because of that we have assigned a new reporter and editor to cover the San Francisco mayoral race. We will continue to aggressively report on this election, including asking tough questions of candidates about their positions and backgrounds.

Audrey Cooper, editor in chief
