The Department of Justice is looking into whether Oakland Mayor Libby Schaaf obstructed justice by warning Northern California residents of an impending raid by U.S. Immigration and Customs Enforcement (ICE). The agency’s acting director, Thomas Homan, told “Fox & Friends” Wednesday morning that the DOJ is “reviewing” whether Schaaf broke any laws by telling her constituents ICE would be raiding the area in order to arrest people violating federal immigration laws.
