Riverbank Councilman Dave White, 71, remains in the intensive care unit of a Modesto-area hospital, city officials said Wednesday.
He may remain in the ICU for a few more days.
White was taken to the hospital June 10 after complaining of tightness in his chest while at a downtown Riverbank restaurant. He underwent surgery that day.
City officials have said he did not have a heart attack. No other information was available about White's condition.
White has been on the council for 18 of the past 25 years and was the city's first elected mayor.
