The San Diego government say they will sue the Trump administration over their releasing of asylum-seeking families who end up in temporary shelters.

Two supervisors said the board voted in a closed session on Tuesday to challenge how the administration had handled the vulnerable families.

They didn't elaborate on grounds for the lawsuit or when it would be filed.

Since late October, the U.S. has been releasing asylum-seeking families at an overwhelming rate such that that charities are relied upon to intervene.

The migrants are not able to make travel arrangements and are merely given notices to appear in immigration court.

The families often end up in shelters run by charities, straining the resources of border towns.

In a statement, board Chairwoman Dianne Jacob said: 'The Trump administration created this crisis by releasing asylum-seeking families into our community without providing critical resources or even places to shelter.'

She said the federal government had failed in its duty to 'consider the impact of its own actions on public health and safety.'

The board also agreed to lease a county courthouse to provide short-term accommodation to families, NBC said.

When migrants are released by ICE officer, local authorities must step in to deal with the problem.

The San Diego Rapid Response Network say that some days this could be 20 migrants and on others as much as many as 200 are released.

The organisation stated they would continue to support the county as they endeavor to support the families 'in exercising their legal, human right to seek safety and protection from violence and persecution in their home countries.'

U.S. Immigration and Customs Enforcement spokeswoman Lauren Mack says the agency doesn't comment on pending litigation.

Previously, the agency has said it has limited authority to detain families, referring to a 20-day cap on holding children.

The Trump administration has acknowledged it separated more than 2,000 families last year through the implementation of a zero-tolerance policy intended to crack down on Central American migration at the U.S.-Mexico border.

Trump officials previously said it would require extraordinary effort to reunite what may be thousands of migrant children who were separated from their parents and, even if it could, the children would likely be emotionally harmed.

An official claimed removing children from 'sponsor' homes to rejoin their parents 'could be traumatic.

Government watchdogs have also said it's unclear how many families were separated in total because agencies did not keep good enough records as the policy was implemented.

Eight immigrant families demanded millions of dollars in damages on Monday including a Guatemalan woman who alleged an officer said her 5-year-old son would be taken and then taunted, 'Happy Mother's Day.'

The claims allege that many children remain traumatized even after being reunited with their parents, including a 7-year-old girl who won't sleep without her mother and a 6-year-old boy who is reluctant to eat.

The Department of Homeland Security did not respond to the claims.
