The Trump administration plans to award nearly half a billion dollars to a Texas nonprofit charged with caring for immigrant children detained at the border, a report said Tuesday.

Southwest Key Programs, which already runs a number of facilities in Texas, will be paid more than $458 million in 2018 to run the detention and car facilities for the Department of Health and Human Services, according to Bloomberg News.

The amount is the highest among organizations, government agencies and companies that run facilities for immigrant children, the news service said.

Nearly 12,000 immigrant children are under the care of the Office of Refugee Resettlement, a Health and Human Services agency.

Southwest Key currently runs a detention facility out of a converted Walmart in Brownsville that shelters nearly 1,500 children.
