William Finnegan on the deportation of an American citizen.

This week in the magazine, William Finnegan tells the story of Mark Lyttle, a U.S. citizen from North Carolina who was deported to Mexico despite ample evidence that he was an American. Michael Agger spoke with Finnegan and his editor, John Bennet, about Lyttle's nightmarish story and what it says about our immigration system. They also looked back at Finnegan's writing career, including his early Profile of Barack Obama and his years reporting from Africa and Mexico. Also, the cartoon editor Bob Mankoff transforms famous paintings into New Yorker cartoons.
