<p>President Donald Trump once left his son, Donald Trump Jr., stranded on a tarmac after he was five minutes late for a flight, the president's first wife Ivana Trump wrote in her new book "Raising Trump."</p> 
<p>Ivana referenced the anecdote when describing a key feature of Donald and the rest of the Trump family that she learned when she and the future president first began dating.</p> 
<p>"The entire Trump clan arrived exactly on time," she wrote. "I learned early on that they were punctual to an extreme. For them, 'on time' meant five minutes early."</p> 
<p>"When Donald arrived in a boardroom, or took his seat on an airplane and the door closed, that was that," she continued. "If you weren't on the inside, the meeting or the flight would start without you. Donald once left Don Jr. standing on the tarmac for being five minutes late to the airport."</p>
