Fortune: Social Media at the Border: Can Agents Ask for Your Facebook Feed? by Jeff John Roberts:
As part of their mission to protect the country, border agents enjoy broad power to question and search anyone entering the U.S. But as more travelers show up with smartphones and social media accounts in hand, some are asking how far this power should extend in the digital age.
The issue arose last year when a new travel form asked foreigners about their social media accounts, and it bubbled up again following Trump’s recent immigration order banning travel by citizens of seven countries. Most notably, an advocacy group filed a complaint with U.S. Customs and Border Protection, claiming agents are subjecting the phones and social media accounts of Muslim-Americans to extra scrutiny.
