More American Jihadis

The Washington Times reports that a senior government official, speaking off the record, has indicated:

The U.S. government is tracking and gathering intelligence on as many as 300 Americans who are fighting side by side with the Islamic State group in Iraq and Syria and are poised to become a major threat to the homeland.

Earlier today we cited a CNN report that the number was near 100. The government should revoke jihadis' passports and leave them overseas; I'm certain legal authority exists to do this. Knowing they cannot return will discourage further ISIS recruiting.
