(CNN) -- Pulitzer Prize-winning journalist and undocumented immigrant Jose Antonio Vargas was detained at a Texas airport Tuesday morning, his spokesman said.
Vargas was held at a detention center at the airport in McAllen, Texas, after he tried to fly out of the border city, his spokesman Ryan Eller said. Information on why he was detained wasn't immediately available.
Vargas wrote and directed "Documented," a film about the U.S. immigration debate and his own life story that CNN aired on June 29.
Vargas' grandfather brought him to the United States from the Philippines illegally when he was 12 years old. Vargas says he didn't know he was in the country illegally until he was 16, when he applied for a driver's license and was told his permanent residency card was bogus.
