ISLAMABAD: US President Donald Trump, who has aggressively campaigned for a Nobel Prize, hailed his peace efforts and joked about not getting the prize at a dinner at the White House on Wednesday, saying Pakistan Prime Minister Shehbaz Sharif got “emotional” while crediting him for saving millions of lives. Venezuelan opposition leader Maria Corina Machado, a 58-year-old industrial engineer, was awarded the Nobel Peace Prize last week. Over the past two years, she has reenergized a politically disengaged population after more than a decade of economic and social collapse.
