Washington: Donald Trump, the Republican presidential nominee, has a track record of achieving the "impossible," his son has said, while his daughter told Americans that his father is a natural-born encourager as the siblings made a passionate push for the candidacy of their dad's race for the White House.
"This is the most important election of our lifetime, one that will determine the future of our country and, in turn, the future of the world," Donald J Trump Jr, 38, said in his address to the Republican National Convention.
"For too long, our country has ignored its problems, punting them down the road for future generations to deal with. In business, I was trained by my father to make the tough investments decisions today to assure a brighter future tomorrow," he said.
"We've actually started to believe that solving our great problems is an impossible task, and that's why we need to elect a man who has a track record of accomplishing the impossible," he added.
"Remember one thing: We're still Americans, we're still one country, and we're going to get it all back. We're going to get it back better than ever before," he said.
"I know we'll get it back because I know my father. I know that when someone tells him that something is impossible, that's what triggers him into action," Trump Jr said amidst applause from the audience.
"I've seen it time and time again, that look in his eyes when someone says it can't be done. I saw that look a little over a year ago when he was told he couldn't possibly succeed in politics. Yes, he did," he said.
He also slammed Hillary Clinton, the Democratic presidential candidate.
"Let me tell you something about risk. If Clinton was elected, she'd be the first president who couldn't pass a basic background check. It's incredible," he said.
"Clinton is a risk Americans can't afford to take. She says she'll issue executive orders to take away Americans' guns. She wants to appoint judges who will abolish the Second Amendment," he alleged.
"She'll throw every possible obstacle in the path of safe, reliable, affordable energy produced in America, by Americans, for American businesses and families. Rather than being energy independent, our country will be forced to remain beholden to her buddies in the Middle East," the Junior Trump said.
Trump's daughter, Tiffney Trump, 22, said: "My dad is a natural-born encourager, the last person who will ever tell you to lower your sights up, give up your dreams."
"I always looked forward to introducing him to my friends, because they meet a man with natural charm and no facade. In person, my father is so friendly, so considerate, so funny and so real," said Tiffney, reflecting the fatherly and humane character of 70-year-old Trump.
"It's often said that with enough effort and determination, you can do whatever you put your mind to, but saying those words and living them are different things, and my father has lived them," she said.
"He motivates me to work my hardest and to always stay true to who I am. That's a great quality to have in a father, and better yet, in the US president," Tiffney said.
