California Sen. Alex Padilla made an unannounced oversight visit to the San Francisco International Airport's windowless 3,000-square-foot immigration holding room, where more than two dozen immigrants have reportedly been held for days at a time since the start of the year. Padilla, Ranking Member of the Senate Judiciary Committee's Immigration Subcommittee, said the facility, operated by CBP, is being used as part of the federal government's mass detention and deportation campaign even though it was not meant to be a long-term detention site, and said constituents had raised concerns that valid green card holders were among those detained without adequate medical care or legal representation. Detainees previously told the San Francisco Chronicle they were not given changes of clothes, slept on upright couches with the lights on, and lacked access to dedicated medical care. SFO had the second-highest number of such airport detentions resulting in transfer to ICE custody, after Miami, according to the Chronicle. This was Padilla's third visit to a California detention facility this year, following earlier visits to the California City and Otay Mesa detention centers.
