What the public record says
Council Member of District 2 - Vicky Santana, Council Member of District 3 - Cathy Warner, and Council Member of District 4 - Aida Macedo is the holder text published for City Council.
That statement is limited to the dated CalRoster field supplied by City of Whittier. Election.org does not infer whether the position is elected or appointed, does not invent term dates, and does not treat the roster as a live feed.
