Two months ago, James Tomsheck was pushed out of his job as internal affairs chief for U.S. Customs and Border Protection.
At the time, authorities criticized him for not doing enough to investigate abuse and corruption.
But now Tomsheck tells a very different story: about a culture that goes out of its way to evade legal restraints.
Use of force by law enforcement agents along the Southwest border has drawn attention and criticism recently, after reports that Border Patrol agents shot and killed unarmed migrants and faced no consequences.
When Congress thinks about border security, it often sees a big, imposing fence.
The federal government has spent $2.3 billion to build the fence — 649 miles of steel fencing, in sections, between the U.S. and Mexico, designed to help control the illegal movement of people and contraband.
It's called tactical infrastructure, and the Border Patrol says it works. But people on the lower Texas border have another name for it: a boondoggle.
A spokesman for the U.S. Department of Health and Human Services says more than 1,800 unaccompanied minor children were processed through Fort Sill in southwestern Oklahoma before the facility was closed last week.
Spokesman Kenneth Wolfe for HHS' Administration for Children and Families says 1,861 minors were processed through Fort Sill. The temporary shelter opened in June and its operations were closed last Wednesday.
Many of the Central American children who have entered the U.S illegally in recent months have come with a heavy burden — a history of hardship and violence. And many of the children now face difficult and uncertain futures.
This has social service agencies around the country scrambling to figure out how to help the more than 30,000 unaccompanied minors who have been placed with family and friends since January, as they await their immigration hearings.
Federal authorities say unaccompanied immigrant children housed at Fort Sill are expected to leave the Army post by Friday.
Kenneth Wolfe of the U.S. Department of Health and Human Services told The Associated Press on Monday the agency can move children from military barracks because it has expanded the capacity of traditional shelters. Wolfe said standard shelters are significantly less expensive to operate.
The agency also says the demand for military shelters was reduced because of a drop in the number of children crossing the nation's southwest border.
