A federal judge in Maryland may soon become the second to block President Donald Trump’s order restricting birthright citizenship from taking effect nationwide.

In last month’s decision limiting one judicial tool, universal injunctions, the court seemed to invite lower courts to use class actions as an alternative.

A federal judge in New Hampshire has granted class-action status to a lawsuit that aims to protect babies who would be denied birthright citizenship under the Trump administration's orders. NBC News' Julia Ainsley reports on the decision and the temporary block it puts into place for President Trump's birthright plans across the country.
