In the United States, the confrontation between the Trump administration and California escalated on Wednesday, as Attorney General Jeff Sessions traveled to Sacramento and attacked California for its so-called sanctuary laws, a day after the administration sued the state over its policies limiting local law enforcement cooperation with federal immigration agents.

Attorney General Jeff Sessions: “So, California absolutely, appears to me, is using every power it has—powers it doesn’t have—to frustrate federal law enforcement. So you can be sure I’m going to use every power I have to stop that.”

Attorney General Jeff Sessions also attacked Oakland Mayor Libby Schaaf, who issued a warning to the community ahead of ICE raids in Oakland last month. On Wednesday, California Governor Jerry Brown accused the Trump administration of declaring war on California and called Attorney General Jeff Sessions a liar.

Gov. Jerry Brown: “And like so many in the Trump administration, this attorney general has no regard for the truth. What he said earlier today is not true. It is a lie. And—but what can I say? We’ve seen in the Trump administration, with the investigations going on, the pleas of guilty to lying by countless individuals, colleagues. So there it is.”
