Hamdi was stopped by immigration officers at San Francisco International Airport on Sunday, October 26, after speaking at an event the previous evening in Sacramento and before a planned appearance the next day in Florida. A U.S. official said his visa was revoked and he is being held in Immigration and Customs Enforcement (ICE) custody “pending removal.”

Detention And Status

Officials confirmed on October 26 that Hamdi was in ICE custody and alleged—without providing evidence—that he posed a “national security threat.” The statement added his “visa was revoked” and that he was held “pending removal,” while advocates insisted due-process standards must be applied.

Advocacy Groups Respond

A prominent Muslim civil-rights organization denounced the detention as an “abduction” and “a blatant affront to free speech,” saying it would contest any removal order. Allies framed the case as part of a broader pattern affecting Palestinian and pro-Palestine voices at U.S. borders in recent months.

Timeline And Venues

According to supporters, Hamdi addressed a gala in Sacramento on Saturday, October 25, then flew to San Francisco, where he was detained the next day; he was scheduled for another event in Florida on October 27. He is 35 and serves as editor-in-chief of a geopolitics publication.

Online Campaigns And Claims

Individuals associated with far-right networks publicly celebrated the detention and claimed credit for pressuring authorities. One U.S. official’s public post referenced “national security,” while activists accused these networks of orchestrating a targeted campaign; neither side provided documentary evidence beyond statements.
