(CNN) A group of lawyers on Wednesday night asked a federal judge to hold the Trump administration in contempt and to order immediate improvements to conditions at Customs and Border Protection facilities where children are being held.

The filing specifically cites facilities in the Rio Grande Valley and El Paso, Texas.

The lawyers are part of a team of doctors and advocates that warned last week of what they said were major health and hygiene problems at Customs and Border Protection facilities in Texas following visits to the facilities.

"Instead, class member children are held for weeks in deplorable conditions, without access to soap, clean water, showers, clean clothing, toilets, toothbrushes, adequate nutrition or adequate sleep. The children, including infants and expectant mothers, are dirty, cold, hungry and sleep-deprived," reads the court filing.

The filing is part of the Flores Agreement, a 1997 agreement that requires the government to release children from immigration detention without unnecessary delay to their parents, other adult relatives or licensed programs.
