(Portland, OR) -- Mayor Keith Wilson is urging Portlanders to volunteer and donate to homeless services, calling this a "pivotal week" in addressing the crisis. His warning comes as a new overnight shelter and day center opened in the Pearl District, drawing both support and criticism from neighbors. Wilson cautioned that federal intervention, like the National Guard deployment in Washington, D.C., could come if local solutions fail. City officials said dozens of people have already stepped forward to help since the mayor's appeal. Police Chief Bob Day added that while federal deployments may be temporary, Portland will need long-term community action.
