Feel good story of the day.

(CNN) — Pulitzer Prize-winning journalist and undocumented immigrant Jose Antonio Vargas suspected he wouldn’t get out.

His fear came to fruition Tuesday morning when he was detained at a Texas airport as he tried to pass through security en route to Los Angeles, his spokesman said. Vargas was being held at a detention center at the airport in McAllen, Texas, spokesman Ryan Eller said.

Official word on why he was detained wasn’t immediately available, but Tania Chavez, an undocumented youth leader who met with Vargas recently and has accompanied him around the McAllen area, told CNN that Vargas was detained because he does not have the proper documentation.

Vargas wrote and directed “Documented,” a film about the U.S. immigration debate and his life story. CNN aired it June 29.

Early Tuesday, Vargas tweeted that he was about to go through security at McAllen-Miller International Airport. Since outing himself as an undocumented immigrant three years ago, he says he has traveled extensively, visiting 40 states.
