Former NBA star Bill Walton took part in a news conference Tuesday morning with the Lucky Duck Foundation to address the issue of homelessness in San Diego. Though the event was to call attention to a new Lucky Duck Foundation initiative, Walton took aim at Mayor Todd Gloria once again. "We need new leadership, Todd Gloria should step aside," said Walton. "Todd Gloria campaigned for his job on the promise he would fix the homeless, humanitarian and public health crisis in our once great city. Todd Gloria has made it worse." CBS 8 reached out to the mayor's office for comment. As of Tuesday afternoon, there has not been a response.
