ICE agents were expected to begin providing additional security duty at select U.S. airports amid the ongoing partial government shutdown that has sidelined many Transportation Security Administration officers. However, there was no immediate indication that any California airports, including San Diego International Airport, would be involved in the effort. Border czar Tom Homan will lead the effort to use immigration enforcement personnel to supplement security at airports across the country. Local officials have objected to the ICE deployment, including a top TSA official at San Diego airport, Aaron Vazquez, who said his job is to make sure travelers are not a threat to security and not to interfere with TSA officers' duties. The shutdown has left roughly 50,000 TSA employees working without pay, contributing to increased absenteeism and staffing shortages at airports nationwide.
