How do you know his son wasn’t ordered to infiltrate the Army?
Don't mine that vein.
I've looked for dirt on the late Captain Humayun Khan, but all I can find indicates he was an officer and gentleman and a leader of men and women who died a true American hero, saving many American lives in the process. He has very convincing character witnesses.
As for the father, well, his appearance on that DNC stage is all you need to know.
His preference for Sharia over that Constitution he was waving around at the DNC is proof we shouldn't want him. But, ironically, if we'd filtered him out, Humayun Khan would still be alive, probably somewhere in the Middle East.
