SACRAMENTO, Calif. _ California opened another front in its legal battle with the Trump administration over immigration policies on Monday as officials announced a federal lawsuit challenging a new rule that allows indefinite detention of migrant children and their families.
The 19-state lawsuit, which is co-led by Massachusetts, was unveiled by Gov. Gavin Newsom and state Attorney General Xavier Becerra, who criticized the president for ignoring a court settlement agreement that limited detention of children to 20 days.
"No child deserves to be left in conditions inappropriate and harmful for their age," Becerra said Monday. "We're taking the Trump administration to court to protect children from the irreparable harm caused by unlawful and unnecessary detention. With our partners across the country, we will fight for the most vulnerable among us."
As the state with the largest immigrant population in the country, including an estimated 2.2 million people in the U.S. illegally, California officials have repeatedly clashed with Trump over his crackdown on migrants, including those seeking asylum.
The lawsuit is the 57th legal challenge filed by California against the Trump administration, 13 of which involve immigration policies, including a dispute over funding for a new border wall.
Immigration issues have been a flashpoint between Trump and California. The administration sued the state in March 2018 to invalidate California's sanctuary laws limiting law enforcement cooperation with immigration authorities, though a federal judge later sided with the state.
The latest legal action is over new regulations rolled out last week that will take effect in two months unless blocked by the courts. The states argue the rules undermine the Flores settlement of 1997, including the presumption that all children are eligible for release into the community.
Acting Homeland Security Secretary Kevin McAleenan said the Flores agreement, which was strengthened in 2015, was responsible for a flood of Central American families coming to the U.S. border and argued the new rules would discourage migration.
"The driving factor for this crisis is weakness in our legal framework for immigration," McAleenan said last week. "This single settlement has substantially caused, and continues to fuel, the current family unit crisis ... until today."
Trump said last week that the policy change was being made on humanitarian grounds.
"Very much I have the children on my mind. It bothers me very greatly," the president told reporters at the White House. "When they see you can't get into the United States ... they won't come. And many people will be saved. Many women's lives will not be destroyed."
The lawsuit announced Monday argues that the new policy interferes with the states' ability to help ensure the health, safety and welfare of children by undermining state licensing requirements for facilities where children are held. The complaint also says the Trump administration rule will result in the vast expansion of family detention centers, which are not state-licensed facilities and have been found to cause increased trauma in children.
The lawsuit says the rule will lead to prolonged detention for children, with significant long-term negative health consequences.
The new policy also violates the due process clause of the 5th Amendment to the U.S. Constitution, the states argue.
The state officials say the regulations remove protections guaranteed by the Flores settlement, which was the result of a class action lawsuit filed in federal court in California alleging substandard conditions of confinement for unaccompanied immigrant children.
That lawsuit, named for migrant Jenny Lisette Flores, ended up with the U.S. Supreme Court before federal officials agreed to a settlement in 1997. The agreement required children be released "without unnecessary delay" to their parents, legal guardians, individuals designated by the parents or a licensed program willing to accept custody, Becerra said.
"It's an assault on the Flores decision," Newsom said last week in an interview on CNN.
"Clearly, I think it will be rejected by the courts," the governor said, adding that "California will once again assert itself in the court of law."
The lawsuit filed Monday came a month after California and other states went to court over concerns that children were being held for weeks without access to basic necessities such as soap, clean, water, toothbrushes, showers or a place to sleep, the attorney general noted.
Also part of the latest lawsuit are the District of Columbia and 18 other states in addition to California: Massachusetts, Connecticut, Delaware, Illinois, Maine, Maryland, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia and Washington.
