Tom Tancredo has a column on birthright citizenship in The Daily Caller:Anwar al-Awlaki and the perils of birthright citizenship

"In the wake of the killing of al Qaida cleric Anwar al-Awlaki, pundits, politicians, and law professors are arguing over whether it’s constitutional for the American government to target an American citizen. Some, such as Ron Paul, have gone as far as calling the killing a potentially impeachable offense.

Lost in this debate is whether al-Awlaki was ever really an American citizen.

Al-Awlaki was born in New Mexico in 1971. Both of his parents were Yemeni citizens in the United States on student visas. As a child, he moved to Yemen along with his parents. He returned to the U.S. as an adult on a foreign student visa."[More]

See my column and Pat Buchanan's column on the same subject. I see Tancredo follows the common practice of referring to the deceased as a "cleric." "Imam" would be a better way of putting it, or "mullah." In any case, Islamic clerics don't share the Christian clergy's tradition of non-combatant status and immunity. Quite the opposite, in fact.
