SACRAMENTO -- Gov. Gavin Newsom and California Attorney General Xavier Becerra Monday announced the state's fight against a Trump administration policy that would allow migrant families to be held in detention for longer periods of time.
The policy, announced last week, would replace an agreement that sets a 20-day limit for holding children who were brought into the country illegally.
California is joining 18 other states to sue the administration over the policy, Newsom and Becerra announced Monday during a Sacramento news conference. Becerra and Massachusetts Attorney General Maura Healey are expected to lead the suit.

The rule, unveiled by acting Homeland Security Secretary Kevin McAleenan, is part of the administration's aggressive effort to revamp immigration laws as the number of families and unaccompanied minors crossing the US-Mexico border has increased.
In recent months, the administration has proposed rules that could make it more difficult for immigrants to get green cards, worked to end temporary protected status for migrants from certain countries and limit avenues to declare asylum.
Under what is known as the Flores settlement, the government is required to release a minor from a non-licensed facility as expeditiously as possible, which has been set at 20 days.
McAleenan said the rule is meant to reduce the number of families trying to enter the US.
"By closing this key loophole in Flores, the new rule will restore integrity to our immigration system and eliminate the major pull factor fueling the crisis," he said at a news conference Wednesday.
The proposal would give the government new licensing authority, allowing the use of either a state license or Immigration and Customs Enforcement detention standards, according to a DHS official, meaning families can be kept longer than 20 days.
McAleenan added that there are three family residential centers with what he described as "campus-like settings" with medical, educational and private housing facilities. The acting secretary said that detained families will have access to indoor and outdoor entertainment, legal counsel, translation services and medical care -- including any immunizations their children might need for later admission to US public schools.
"The facilities that we will be using to temporarily house families under this rule are appropriately, fundamentally different than the facilities where migrants are processed following apprehension or encounter at the border," McAleenan said.
The regulation is facing legal challenges and must also be examined by the judge who oversees the Flores settlement. It will take effect 60 days after it is formally published later this week.
"This is yet another cruel attack on children, who the Trump administration has targeted again and again with its anti-immigrant policies," said Madhuri Grewal, policy counsel for the American Civil Liberties Union. "The government should not be jailing kids, and certainly shouldn't be seeking to put more kids in jail for longer."
Responding to questions about when the new rule will be rolled out, McAleenan acknowledged that the administration will likely face litigation before adding that they hope to implement it as soon as possible which could mean eliminating the Flores settlement agreement.
"We are not going to be detaining every family unit that arrives starting tomorrow," McAleenan said.
There has been a major influx of families and children apprehended at the southern border in recent months. Already this year, more than 430,000 family members have been arrested for crossing the southern border illegally, compared to around 100,000 for all of last year.
