The debate over a proposed downtown sports and entertainment district is heating up again at San Antonio City Hall, with Mayor Gina Ortiz Jones pushing for another public vote on the city's funding for a new Spurs arena.

The renewed fight comes as the city faces a projected $158 million budget shortfall and council members debate how to close the gap.

The latest dispute began July 31, when Jones sent a memo proposing that San Antonio voters get another opportunity to vote in November on public funding for a downtown arena for the Spurs.
