President Donald Trump's deportation henchmen appear to have dramatically increased the use of Coast Guard aircraft to transport immigrants, according to flight data, activist flight trackers and video confirmation. Since June 23, the majority of flights operated by the Coast Guard C-27J Spartan fleet -- at least 263 flights -- are likely to have been for Immigration and Customs Enforcement (ICE), transferring immigrants to and from ICE's nexus of detention centers in Alexandria, La., Harlingen, Texas, and the Florida Everglades camp known as "Alligator Alcatraz," according to an analysis of public flight data.
