Does CBP have access to domestic Amtrak reservations?
Documents released to us by Amtrak suggest that since 2012, US Customs and Border Protection (CBP) has had direct access to Amtrak’s reservation system, possibly including access to reservations for Amtrak passengers traveling entirely within the USA.
What do these documents show? And why would an immigration and border patrol agency want access to records of travel by US citizens and other residents within the borders of the US?
