Transportation Security Administration officials alerted Immigration and Customs Enforcement that Angelina Lopez-Jimenez and her 9-year-old daughter were traveling to Miami, leading to their detention at San Francisco International Airport. The Guatemalan mother and child were flagged when they appeared on a passenger list for a Sunday flight from San Francisco to Miami, according to federal documents.

Lopez-Jimenez, 41, had been living in Contra Costa County with no criminal history but had entered the country illegally. She came to the government's attention during Trump's first term in 2018 when Border Patrol agents apprehended her near the Arizona border. An immigration judge ordered her deportation in 2019 after she missed a hearing, but no action was taken until this week.

The TSA's sharing of passenger information with ICE has raised concerns among Democratic officials. Representative John Garamendi condemned the data sharing as "omnipresent" under the Trump administration, saying it bypasses due process. The mother and daughter were deported to Guatemala within 36 hours of their detention, highlighting how airports have become new fronts in immigration enforcement.
