New York should lead a legal defense of the U.S. Census counting non citizens in its upcoming count of the population next year, Attorney General Letitia James said on Monday.

The counting of non-citizens residing in the United States was challenged last May by the state of Alabama and a congressman from the state. The defendant in the case is formally the U.S. Department of Commerce, but New York is moving to intervene in the case.

New York is intervening under the pretense that President Donald Trump’s administration will not muster an adequate defense of the Census. Trump withdrew an effort to require a citizenship question on the Census, which advocates worried could lead to an undercount.

The state will lead a 26-member coalition that includes 15 states, the District of Columbia, three counties, six cities and the U.S. Conference of Mayors.

“No individual ceases to be a person because they lack documentation,” James said in a statement.

“The United States Constitution is crystal clear that every person residing in this country at the time of the decennial census — regardless of legal status — must be counted, and no matter what President Trump says, or Alabama does, that fact will never change. So we are intervening in this case and taking on the role of defendant because the values enshrined in the U.S. Constitution deserve better than a halfhearted and inadequate defense. We will continue to lead this fight because, despite the Trump Administration’s previous racist and xenophobic attempts to tip the balance of power in the nation and Alabama’s endeavor to continue down that path, we will never stop fighting to ensure every person counts.”
