WASHINGTON, D.C.: Veterans groups and Republicans on Monday (Tuesday in Manila) savaged Donald Trump’s war of words with the parents of a slain Muslim American soldier, the latest example of the presidential nominee making statements considered beyond the pale. The feud has shaken the US presidential campaign, becoming a flash point 99 days before the November election that pits the Republican against Democrat Hillary Clinton, whom Trump on Monday (Tuesday in Manila) called “the devil.” Criticism has poured in from outraged veterans groups, relatives of soldiers killed in action and even President Barack Obama. The episode has dominated US headlines since last Thursday (Friday in Manila), when Pakistani immigrant Khizr Khan galvanized the Democratic National Convention with a tribute to his dead son in which he rebuked the Republican nominee for having “sacrificed nothing” for the country. In an interview aired on ABC Sunday (Monday in Manila), Trump insisted he had made “a lot of sacrifices” while suggesting that Khan’s wife, who stood silent on the convention stage as her husband spoke, had not been allowed to talk. On Monday (Tuesday in Manila), Trump renewed his assault, tweeting: “Mr. Khan, who does not know me, viciously attacked me from the stage of the DNC and is now all over TV doing the same – Nice!” The families of 23 other slain US soldiers berated Trump for remarks they called “repugnant and personally offensive.” “We feel we must speak out and demand you apologize to the Khans, to all Gold Star families, and to all Americans for your offensive, and frankly anti-American, comments,” they said in an open letter.
