The Trump administration’s request for deeper access comes after the U.S. border agency in December proposed reviewing five years of social media history. Talks are happening as the U.S. Immigration and Customs Enforcement (ICE) service is under heavy scrutiny for its use of surveillance technology against protesters in cities such as Minneapolis.

The negotiations should be “put on hold” until the security and privacy of citizens in the EU and U.S. can be guaranteed, liberal European Parliament member Raquel García Hermida-van der Walle said in an interview.

Romain Lanneau, a legal researcher with surveillance watchdog Statewatch, said police databases in Europe could contain information on anyone from protesters to journalists who might be considered a “threat,” and that — under the deal being discussed — this information would be at the fingertips of U.S. border authorities who could refuse those people entry to the United States or even detain them.

European regulators are “very cautiously looking at what’s happening in the United States,” Wojciech Wiewiórowski, the EU’s in-house data protection supervisor, told POLITICO. Europe “has to be careful” about how it allows the data of Europeans to flow to the U.S., he said. 

Hermida-van der Walle in January co-signed a letter by six prominent lawmakers calling on the Commission to stand down given the “current geopolitical context,” despite Washington’s admonition that failure to reach a deal will mean Europeans lose access to its visa waiver program.

Unprecedented access

The U.S. is seeking access to information including biometric data such as fingerprints that is stored on national databases in European countries, according to an explanatory note sent to national experts. The data would be used to “address irregular migration and to prevent, detect, and combat serious crime and terrorist offences,” the note said.
