Boy in Soviet military costume causes outrage at Trump's White House Halloween celebration: A boy in a Soviet tank uniform and a girl in a Russian summer dress at the White House Halloween turned out to be the children of the White House deputy chief of staff for policy. "Donald and Melania Trump met children on the south lawn of the residence and handed out candy. Among the guests were a boy in a Soviet-style cap with a tank soldier's chevron and a girl in a sundress with a kokoshnik-like headdress. Melania noticed the boy's hat and touched it. Miller himself was also present at the celebration."
