A poised, articulate and ever-measured counterpart to her father's brash, freewheeling style, Ivanka will introduce the Republican presidential nominee in Thursday night's grand finale of the party's convention. She will be the last of four Trump's children to speak — and the last to have the chance to humanize her polarizing father for the American people, showing warmth between his rougher edges and heart behind his bluntness.

"There is no one closer to my father than Ivanka," her brother, Don Jr., said in an emailed statement. While he said his father is close with all of his siblings, Don Jr. said "his bond with Ivanka is truly unique. No one is more poised and articulate than my sister and no one will do a better job of explaining to the American people who my father really is."
