Oregon on Tuesday joined a growing list of Democratic-led states suing the Trump administration over its efforts to roll back birthright citizenship in the country.

Trump's executive order titled “Protecting the meaning and value of American citizenship” aims to end automatic birthright citizenship. The Fourteenth Amendment establishes birthright citizenship, meaning any child born in the U.S. is a citizen, regardless of their parent’s status.

Washington, Arizona and Illinois joined Oregon in one case, while California and other Democratic states filed a separate lawsuit.
