An officer contracted by the Federal Protective Service of the Department of Homeland Security was shot and killed Friday night in Oakland, California, the FBI said in a statement.
A second contract officer was also injured and is in critical condition, acting Homeland Security Secretary Chad Wolf said during a news conference Saturday.
"As of late we have witnessed an outright assault on our law enforcement community. Last night in Oakland, California an assassin cowardly shot two Federal Protective Service contractors as they stood watch over a protest," Wolf said.
"Let me be clear when someone targets a police officer or a police station with an intention to do harm and intimidate, that is an act of domestic terrorism," DHS Acting Deputy Secretary Ken Cuccinelli said during a news conference Saturday.
