Democratic attorneys general are vowing to uphold the constitutional protection of birthright citizenship following President Donald Trump’s attempt to do away with it via executive order.

After being sworn into office on Monday, Trump signed an executive order overhauling birthright citizenship in the United States despite it being a constitutional right under the 14th Amendment. Several attorneys general, including California Attorney General Rob Bonta, Arizona Attorney General Kris Mayes, and New Jersey Attorney General Matthew Platkin, have vowed to uphold the right and find legal routes to fight the order.
