"We are writing on behalf of the 3,400 professional writers who are members of PEN American Center to express our outrage that German publisher and PEN member Karl-Dietrich Wolff was recently denied entry to the United States," the letter states. "With no explanation, he was reportedly questioned for six hours, photographed and fingerprinted, and then was forced to return to Frankfurt on the last outbound flight."
"He was on his way to the United States this past week at the invitation of Vassar College to speak about the civil rights movement and 20th century Germany," PEN writes.
"It was our hope that the change of administrations would lead to a review of this practice and an end to incidents like the one Mr. Wolff experienced this past week in New York," the letter also states.
Update: We also came across Cappy's official statement.
