Nebraska's governor and most of its congressional delegation have asked federal officials for information about more than 200 unaccompanied immigrant children who have been placed with relatives or sponsors in Nebraska.
The children are among tens of thousands who have crossed the southern U.S. border illegally and unaccompanied by parents during the recent children's migration from Central America.
A letter addressed Monday to U.S. Department of Health and Human Services Secretary Sylvia Burwell says the agency's handling of matter lacks transparency and coordination with states and local governments.
The letter was signed by Gov. Dave Heineman, Sens. Deb Fischer and Mike Johanns, and Reps. Adrian Smith and Lee Terry. Rep. Jeff Fortenberry didn't sign the missive.
Last week Heineman expressed outrage that federal officials had refused to share the information.
