"If there is an Arab-American family being rounded up without benefit of an attorney ..."
Say what? I'm having a hard time believing any such thing ever happened, but it surely doesn't happen routinely. Note that Obama uses the specific wording "Arab-American family" -- not an individual, not someone here on a work or student visa, but an Arab-American family, a phrase which to me signifies actual U.S. citizens, or at least long-term legal "green card" residents.
If any such persons indeed have been "rounded up without benefit of an attorney," Obama's campaign had better be prepared to provide their names and documentation of their case, because otherwise he's making a very harmful and irresponsible accusation.
It's almost as if he's trying to hand the nomination to Hillary.
UPDATE: Atlas Shrugs makes an obvious point: "CAIR would be screaming bloody murder."
