"Through his essential authenticity, disarming wit, and unwavering commitment to faith, family, and country, President Bush inspired generations of his fellow Americans to public service - to be, in his words, "a thousand points of light" illuminating the greatness, hope, and opportunity of America to the world", Trump wrote.
He added, "President Bush always found a way to set the bar higher".

"Traveling overseas, I also came to appreciate the reputation Bush had built over many years", he wrote.
