US Customs and Border Protection stopped 1,903 people for secondary inspection in the 9 days it enforced President Donald Trump’s first travel ban, a new document made public by the agency shows.

The vast majority of those stopped — 1,457 people — were lawful permanent residents, a group of people caught up in the confusion surrounding Trump’s issuance of the order barring travel from seven Muslim-majority nations on Jan. 27, 2017, without warning.

Of the remaining 446 people subject to secondary inspection, more than 1/4 of them — at least 134 — withdrew their entry request. Such a move would have required them to leave the country immediately.
