On Sunday, I woke to a series of emails and posts from legal groups, reporting that American citizens who had been born in Iran or had Iranian ancestry, including children and the elderly, were being denied entry into the US and held at a United States Customs and Border Protection (CBP) facility at the Peace Arch in Washington State. Everyone was seeking information about how many people were affected. They also wanted to know whether there was new guidance to the CBP about how to treat Iranian-Americans and whether the problems were isolated to the Peace Arch border station or were happening nationwide. Group members were reaching out to lawyers in Seattle, elected officials, newspapers, and others, trying to get credible first-hand information. I spent a portion of the morning connecting these groups to each other and sharing information as it came in.
