WASHINGTON (AP) — The U.S. government withdrew Thursday from settlement negotiations to end lawsuits filed on behalf of parents and children who were forcibly separated under the Trump administration's zero-tolerance border policy, the American Civil Liberties Union said.

Justice Department officials informed lawyers for the plaintiffs in a conference call that the government would not offer a global settlement in family separation cases and will defend each individual suit in court, said ACLU attorney Lee Gelernt.

The decision comes after eight months of negotiations and weeks after reports of a proposed settlement that would include payments of several hundred thousand dollars to each family sparked outrage among Biden administration critics in Congress and elsewhere.

Gelernt said no explanation was given. "It's hard to understand DOJ's decision other than it was influenced by political considerations," he said.

The Department of Justice did not immediately respond to a request for comment.

About 5,500 children were forcibly removed from their parents in 2017 and 2018 under President Donald Trump as his administration sought to stop an increase in people crossing the U.S.-Mexico border with criminal prosecutions, even if the migrants were presenting themselves to authorities to seek asylum as permitted under the law.

The parents of hundreds of children have still not been located.

Trump halted the practice in June 2018 amid widespread outrage, including from many Republicans, just six days before a judge ordered an end to the program in response to a lawsuit filed by the ACLU.

The settlement talks with the ACLU and attorneys for hundreds of other plaintiffs had proceeded quietly until The Wall Street Journal reported in October that the Justice Department was considering paying about $450,000 to each family affected by the policy. The Associated Press later confirmed the figure had been under consideration.

The suits filed under the Federal Tort Claims Act are intended to help compensate families for the psychological damage of the separation, but critics argue it would reward people for illegally crossing the border.

"Little children were deliberately abused by our government, yet the Biden administration is now going to defend the practice in court," Gelernt said. "That is shameful."

Asked about the amount on Nov. 3, Biden appeared to misunderstand the question and said a payment of about $450,000 per person was "not going to happen." He later said he supported a settlement, without specifying an amount.

In defending against the suits, the Biden Justice Department will also be defending senior Trump administration officials named individually in the ACLU suit, including former senior adviser Stephen Miller and former Attorney General Jeff Sessions.
