A federal judge questions the Trump administration on implementation plans for controversial birthright citizenship executive order as advocacy groups file class action lawsuits in response.

The Supreme Court ruled 6-3 on Friday to curtail federal judges’ authority to issue nationwide injunctions against President Donald Trump’s executive order ending automatic birthright citizenship, though the policy’s future remains unclear as litigation continues in lower courts.

President Donald Trump's administration sued Los Angeles on Monday over policies limiting city cooperation with federal immigration authorities, continuing a confrontation over the Republican's deportation efforts in a largely Democratic city.

The Trump administration alleges in federal court that the city's sanctuary ordinance violates the Constitution by "thwarting" immigration enforcement.
