From [HERE] The private prison industry -- one of the most controversial pieces of the US carceral state -- has essentially recovered a year after the Obama administration sent a chill down its spine.

Last August, then-Deputy Attorney General Sally Yates issued a memo calling on the Department of Justice to begin curtailing its use of private prisons -- incarceration run by for-profit companies.

Stocks for one of the two major publicly traded prison companies nosedived, and with a presidential victory for Democratic nominee Hillary Clinton widely expected, the Yates memo seemed to indicate the heyday for the private prison industry had passed.

But the impact of the decision was not lasting.

On November 8, Trump won the presidency, and just days into the job, Attorney General Jeff Sessions rescinded Yates' guidance.

The private prison industry saw stock prices soar for months after the election even relative to the already robust stock market.

And one year ago Friday, from that now-rescinded memo, the situation for these prisons looks largely like what it was before the Obama-era Justice Department sought to change the status quo.

Critics of private prisons contend they are inefficient and inhumane.

When she issued her memo, Yates cited a government watchdog report that said private prisons were generally more expensive and offered worse results. Groups such as the ACLU lauded the report and Yates' decision while the private prison industry reeled. It called the report imbalanced and challenged its comparison of private and public facilities.

Following years of relatively low crime rates and the more recent dip in the prison population, Sessions has pushed for a crackdown on drug and gun offenses and offered a wholesale endorsement of Trump's "law-and-order" campaign.

The companies

When it comes to private prisons in the US, the two biggest names are CoreCivic -- the new name for the Corrections Corporation of America -- and GEO Group. Management & Training Corporation, another company with prison operations, is not publicly traded.

While CoreCivic and GEO Group have, for the time being, seen a halt to their massive surges since the election, both in their second quarter earnings calls said they expected more federal contracts as the departments of Justice and Homeland Security detain more people.

Both companies welcomed the Trump era with large donations.

In January, GEO Group's Pablo Paez, the company's vice president of corporate relations, told USA Today it donated $250,000 to Trump's inaugural committee. OpenSecrets' list of inauguration donors noted the GEO Group donation, as well as CoreCivic's $250,000 contribution.

The month before the election, GEO Group hired two former Sessions aides as lobbyists: David Stewart and Ryan Robichaux, according to Politico.

The Bureau of Prisons renewed two large contracts for GEO Group in May, and CoreCivic said in its second quarter earnings call it expected the Trump administration would mean more contracts for the company.

Private prisons and immigration

Private prison companies overall make up a small share of the incarceration pie, both on the federal and state levels, Justice Department data show. This means while private prisons are significant, they don't account for most of mass incarceration facilities.

A large share of people locked up in federal private facilities are criminal undocumented immigrants, and populations at the local level vary wildly depending on the state. Many states have no private institutions while others contract with these companies for a sizable share of their prisoners.

So when it comes to the Trump administration, these prison contractors are eyeing both criminal law enforcement and immigration. But on both counts, the people going to private prisons paid for by the federal government are largely immigrants.

From Day One of Trump's campaign, he pushed heavily for a crackdown on undocumented immigration, and once in office, Trump ordered Immigration and Customs Enforcement to ramp up its enforcement efforts.

For years, ICE has outsourced the bulk of its detention operations to the private sector.
