President Trump’s Commerce Secretary Wilbur Ross has been hit with a new lawsuit in Manhattan federal court over a controversial citizenship question that’s to be added to the 2020 census.

A slew of immigrants’ rights groups, including the New York Immigrant Coalition, filed the suit Wednesday, charging the Department of Commerce, Ross and the Bureau of Census of purposefully seeking to harm immigrant communities and people of color with a question about their citizenship.

“The addition of the citizenship question is a naked act of intentional discrimination directed at immigrant communities of color that is intended to punish their presence, avoid their recognition, stunt their growing political power, and deprive them and the communities in which they live of economic benefits,” according to the lawsuit filed by the American Civil

Liberties Union, the New York Civil Liberties Union, and the Arnold & Porter law firm.

They also claim it will thwart the constitutional mandate to accurately count the U.S. population by discouraging immigrants from answering census questions.

The lawsuit is asking the court to declare the question unconstitutional and to bar the Census Bureau from asking it when it goes door to door collecting data on the US population.

In March, Ross ordered that the 2020 Decennial Census include a question about the citizenship of all U.S. residents for the first time since 1950 — leading to a slew of lawsuits around the country, including those filed by the California attorney general, Eric Holder’s National Redistricting Foundation and the Lawyers’ Committee for Civil Rights Under Law on behalf of the City of San Jose.
