The squabble between Oakland and federal immigration officials is looking more like an all-out war.

Immigration and Customs Enforcement Director Thomas Homan blasted Mayor Libby Schaaf on Wednesday for her controversial decision to alert members of the public about impending immigration raids in and around the city. During an appearance on Fox News, Homan likened Schaaf to a ‘gang lookout’ and said his agency was unable to locate 800 criminals because of the warning.

As City News noted Tuesday, some critics have accused Schaaf of obstruction of justice.

But many critics of the administration, including House Speaker Nancy Pelosi (D-San Francisco), say ICE has lost focus on the pursuit of serious criminals, instead breaking up families as a means of intimidating the country’s undocumented communities.

“This raid was intended solely to terrorize innocent immigrant families and instill fear in the hearts of our communities,” Pelosi said, “not to keep Americans safe.”

Shcaaf also shot back, defending her position and calling the recent raids “racist.”

Meanwhile, hundreds of protestors descended on ICE’s building in San Francisco Wednesday in opposition to the recent sweeps that netted some 150 people. See coverage of the protests here.
