The ACLU of Maine is joining its New England counterparts to sue President Donald Trump over his order to end birthright citizenship.

His order says the federal government won’t recognize the birthright of children born to parents who are in the country illegally.

A statement from the ACLU of Maine says birthright citizenship is guaranteed in the 14th Amendment.

“If you’re born here, you are a citizen – period,” said the statement. “No politician can decide who is American and who is not. The 14th Amendment guarantees the citizenship of all children born in the United States regardless of race, color, or ancestry. It was ratified in 1868, overturning the Dred Scott decision that denied Black Americans the rights and protections of U.S. citizenship.”

The order from President Trump was expected to receive immediate legal challenges from civil rights and immigration activist groups.
