The Chinn exception to the Trump ban (an exception ordered by the Suprme Court of the United States) would have had nothing to do with Syed Farook's wife. She was not from one of Trump's list of six countries to which his travel ban applied. Therefore the Supreme Court's exception for relationships would not come into play. Trump leaving her country off the banned list could have been a cause in your example but not the SCOTUS/Chinn relationship exemption which would not have come into play.
