Amid an ongoing debate over whether a pair of private companies will continue to operate the city of Denver’s community corrections facilities, a Denver city councilwoman has tweeted out what purports to be a letter describing poor conditions at one of the halfway houses, and another saying residents are being used to fix up a facility.

In one letter posted by City Councilwoman Candi CdeBaca, an alleged halfway-house resident says that the facility where the writer lives has overflowing toilets and a lack of proper food and eating utensils.

In another letter posted by CdeBaca, the writer claims that since the Denver City Council voted not to renew a contract with the halfway-house operators, residents have been made to clean and beautify the facility to make it look more presentable.

“I am watching them right now put lipstick on the pig and it sucks that we are being made to be slave labor because they have not taken care of this place for years,” the letter reads.

CdeBaca, who tweeted out photos of the letters, later referenced them when commenting on Mayor Michael Hancock’s recent visit a community corrections facility, as reported by KCNC-CBS4.

” … current residents being warehoused in these facilities [are] telling us the corporations are forcing them to scramble to ‘fix up’ the buildings to prep for the Mayor’s visit….and only the best staged get a visit,” she posted.

Greg Mauro, head of Denver’s Division of Community Corrections, which supervises the halfway houses, denied allegations that the halfway houses are in disrepair and told Denverite that the claims will be investigated.

CdeBaca, a council newcomer, is among the City Council members who voted Aug. 5 to end contracts worth more than CoreCivic and GEO Group, which run six community corrections facilities in the city.

These companies also operate private prisons across the U.S. and have contracts with Immigration and Customs Enforcement to run immigrant detention facilities, including a GEO facility in Aurora that has been the target of protests over Trump administration immigration policies.

Closure of the residential-style Denver facilities could mean that nearly 500 residents would either be sent back to state prisons or released early on parole.

The council is expected to vote Monday on whether to extend the contracts on a short-term basis. Meanwhile, a 13-member advisory committee will pursue new options for halfway house contracts and make its recommendations by next Jan. 31.
