Muhammad Ali's son says he felt "violated" when immigration officials questioned him about his religion at a Florida airport.
The boxing great's namesake, Muhammad Ali Jr., says his detention shows some of his father's civil rights battles are still being fought.
Ali Jr. commented on the Feb. 7 incident on Monday. He said he was appalled that as a U.S. citizen he was asked about his religion.
Ali Jr. and his mother, Khalilah Camacho Ali, said they were pulled aside and separated at Fort Lauderdale-Hollywood International Airport as they returned from a trip to Jamaica.
U.S. Customs and Border Protection spokesman Daniel Hetlage confirmed that Ali Jr. was held for questioning by customs officers, but said it wasn't because he's a Muslim or his Arabic-sounding name.
