Lockyer attended Tuesday's regularly scheduled supervisors meeting. She returned to work last week after treatment for alcohol abuse, which followed her claim that she was assaulted by her ex-boyfriend in a Newark motel.
Colleagues in county government say Lockyer looks strong and healthy.
"She's a very vibrant, young, rising star and we really hope the best for her to get back on track with all the initiatives that are so important for her like St. Rose Hospital and domestic violence and things like that," said Alameda County District Attorney Nancy O'Malley.
The 40-year-old Lockyer is the wife of State Treasurer Bill Lockyer.
