The US immigration detention has ballooned since the turn of the millennium, doubling in size between 2000 and 2010 amidst a national crackdown on immigration. The bloated system, run largely by private, for-profit prison companies,currently incarcerates men, women, and even children, and the detention centers have been plagued by allegations of abuse, medical neglect, and sexual assault.
In a significant departure from the Obama administration's policies, Clinton has pledged to close these private-run detention centers. She has also promised to close the family detention centers opened by the Obama administration in 2014 in response to an influx of children and mothers seeking asylum from violence-plagued countries in Central America.
Immigration advocates aren't totally satisfied, pointing out that Clinton has not actually promised to decrease overall detention of undocumented immigrants. "We don't think immigrant detention should exist," said Christina Parker, who directs immigration programs for Grassroots Leadership. "There's a strong argument that the only reason immigrant detention so large is to profit two or three companies. So if you believe that then there would be no reason for them to exist after private contracts ended."
Parker added that the Democratic candidate should specify "how exactly and when exactly" the facilities would shut down. So far, Clinton has not. Read more about Everything You Need to Know About Hillary Clinton's Immigration Plans
