The number of ICE detainees exceeded 70,000 for the first time in the deportation agency's 23-year history, according to internal DHS data obtained by CBS News.
… No prior administration had ever held an average of more than 50,200 people per day in immigration detention (in FY 2019, during Trump’s first term). As of September, detainees spent an average of 44 days in immigration detention, with each detention averaging $152 per day.
