He supports private prisons though, he cited building them as one of his greatest achievements as governor. Presumably he won't be happy with this decision.
this is true, however he wrote in his personal blog that:
"Never in that process did I experience any pressure to “fill beds” in the private prisons we built. And if I had, it wouldn’t have worked. It might happen elsewhere, but it absolutely did not happen in New Mexico when I was Governor. At the time, the “per-prisoner” cost in the state prisons was $76 per day. The cost to house prisoners in the private facilities was $56 per day. Better service, lower cost."
