Ozturk was suddenly arrested by plainclothes federal agents Tuesday in an incident captured by a surveillance camera.

The U.S. Department of Homeland Security accused Ozturk, a Turkish national, of "activities in support of Hamas."

Secretary of State Marco Rubio suggested Tufts PhD student Rumeysa Ozturk's visa was revoked over her pro-Palestinian activism — though he gave no evidence it was anything more than an op-ed in the Tufts student newspaper.
