Zahr Said didn’t think much about her inability to check in online for her flight home to Seattle after an October business trip in Beijing. She also didn’t worry too much about being twice singled out for additional screening before boarding her flight and again at the U.S. Customs and Border Protection checkpoint at Seattle International Airport. The University of Washington law professor assumed the heightened security measures might have been linked to an annual weeklong Communist conference in China. But when she had similar difficulties checking in for an October 26 flight to Irvine, California, Said realized it was more than just an anomaly. She was puzzled that, despite having Global Entry clearance, which allowed her expedited entry through airport security and customs, she had become a target for airport questioning and invasive pat-downs.

Three days later, Said got an email from CBP notifying her that her Global Entry clearance had been revoked. Said spoke to the enrollment office at the Seattle airport, which told her that the revocation came from a higher office responsible for vetting procedures, she said.

“I live in Seattle. I have children. I have two stepchildren. I have a husband. I teach yoga.” Said, 41, told The Intercept. “It all makes me who I am — and I feel all of those things evaporate in a second when TSA or CBP seem to make it about me having a Yemeni father or being born in Lebanon.”

But Said is not alone. She is one of hundreds of travelers with a Muslim, Arab, or South Asian background whose Global Entry clearances were revoked, in what lawyers and civil rights activists say is a de facto extension of the Trump administration’s Muslim travel ban.

The American-Arab Anti-Discrimination Committee in August and October obtained emails and documents through the Freedom of Information Act confirming that CBP revoked Global Entry memberships for hundreds of travelers from Arab and Muslim-majority countries – many of them U.S. citizens — earlier this year. And ADC’s own records show that the number of revocations exceeds what CBP has acknowledged.

Global Entry is one of four CBP Trusted Traveler Programs that allow vetted U.S. citizens, lawful permanent residents, and nationals from nine countries expedited entry through airport security and customs. In order to obtain Global Entry clearance, applicants must provide biometric records and undergo interviews and background checks. Days after President Donald Trump signed a hotly contested executive order restricting immigration from seven Muslim-majority countries, about 30 Muslim and Arab travelers in the United States reported to ADC that CBP revoked their Global Entry clearances, according to immigration attorneys Andrew Free and Greg Siskind, who filed a lawsuit on ADC’s behalf.

“What has happened, in practice, is that people who were once able — by the virtue of Global Entry — to escape the constant racial and ethnic profiling they faced when traveling have now been suddenly, and without explanation, denied that privilege,” Free told The Intercept. “The only thing they all have in common is that nothing has changed in their own personal situations, and, of course, the reality of their own identities.”

In March, ADC filed a FOIA request with CBP for emails that contained the terms “Muslim,” “Arab,” “Muslim ban,” “ban,” and “travel ban.” CBP did not timely respond to the request, so ADC filed a lawsuit in April. On October 6, nearly six months later, CBP released records to the ADC. The response, Free said, is incomplete and misleading. For example, CBP only turned over emails from a single CBP manager’s email account, and they did not contain any of the keywords included in ADC’s request. CBP also has not conducted requested email searches that would reveal whether the agency issued any internal policies or memoranda on or after November 9, 2016, relating to the suspension, revocation, or cancellation of Global Entry memberships.
