The lawsuit was filed in New York federal court by Democratic attorneys general of 15 states including New York, Illinois and Hawaii, as well as the District of Columbia. The lawsuit, which was filed this afternoon in the U.S. District Court for the Eastern District of NY, details how the Trump administration has violated the Equal Protection clause of the Constitution by discriminating against DREAMers of Mexican origin, who make up 78 percent of DACA recipients; violated Due Process rights; and harmed States' residents, institutions, and economies.
"Ending this policy represents an assault on the values that built this state and this nation", Gov. Cuomo said in the statement.
The lawsuit, filed in U.S. District Court in Brooklyn, seeks to preserve former President Barack Obama's 2012 executive order creating the Deferred Action for Childhood Arrivals program, or DACA.
He added: "These DREAMers play by the rules".
They called DACA an unconstitutional abuse of executive power, but proponents of the programme said the move by Mr Trump was cruel.
"(DACA) is a program that has protected from deportation approximately 800,000 young people who grew up in this country, most of whom have known no other home than the United States", the lawsuit said.
Taking advantage of this momentum, Eric Schneiderman is announcing the multi-state lawsuit in a press conference at 2:15pm Wednesday, which will be livestreamed on his Facebook page.
NY is home to almost 42,000 DACA grantees.
The investigation is the latest effort in the Attorney General's Suburban and Upstate Response to the Growing Epidemic Initiative, a commitment to collaborating with state and local law enforcement to root out violent gangs and drug dealers.
"... More than 78 percent of DACA grantees are of Mexican origin, which is more than double the percentage of people of Mexican origin that comprise of the overall foreign-born population (29 percent) of the United States".
The problem, according to Schneiderman, is that users don't know how much Fentanyl may be in one, thus anyone who takes one is "playing Russian Roulette".
The program, which Trump challenged Congress to salvage with legislation, grants the immigrants the legal permission to travel and work.
They also ask a judge to prevent the federal government from using information obtained through DACA applications to "identify, apprehend, detain, or deport" any of those applicants or their family members.
"Immigration is the lifeblood of New York State".
