Khizr and Ghazala Khan and their young children had lived in Houston all of a few hours - their new home near Fairbanks and U.S. 290 bare, lacking even a refrigerator - when they experienced what they would come to view as America's defining values. The Khans catapulted into the national consciousness in late July, when, in the bright spotlight of the Democratic National Convention, Khizr Khan - a preternaturally calm attorney - confronted Republican nominee Donald Trump and his proposed ban on Muslim immigrants by pulling a copy of the Constitution from his pocket and intoning to Trump, "You have sacrificed nothing and no one." The frenetic pace of the national spotlight has hardly slowed for the Khans, who declared their visit as honorees at the local Islamic Society's annual fundraiser a "homecoming" to the city where they lived a happy first four years in America, beginning in 1980.
