Mark Bray has become one of the highest-profile people caught up in Donald Trump’s efforts to target Antifa

Baggage dropped and boarding passes in hand, Mark Bray and his family cleared security at Newark airport in early October. Their flight to Spain was meant to ferry the family of four to safety after days of mounting threats; instead, as they waited at the gate to board, they were told that someone had cancelled their reservation.

“It felt like I was being watched and laughed at,” said Bray, a professor at Rutgers university who teaches a course on the history of antifascism and in 2017 wrote a book on Antifa. “I knew it was politically motivated one way or the other.”
