I want to know the answer to the following question:
When did a mediation process begin between Filner and a city representative?
All the background I'm provided with is that "On August 19 Filner and city representatives entered a mediation process, as a result of which Filner agreed to resign, effective August 30, 2013, while the city agreed to limit his legal and financial exposure.". Is that enough to answer the question?
Answer: yes
