Katy Perry, Jason Derulo and Stevie Wonder were all there - but the only guest who got to give President Barack Obama a hug during his speech was restaurant owner Tim Harris. Harris has Down syndrome, but he owns his own restaurant and is a Special Olympics star in year-round sports. And the focus was more on the star athletes than on the pop stars at a White House event on Thursday to commemorate the anniversary of the Special Olympics organization. "Presidents need encouragement once in a while too...Thank you, Tim," Obama said after Harris left his seat during the president's remarks to give him a hug, Harris' trademark at his restaurant in Albuquerque, New Mexico. Established in 1968, the Special Olympics give people with intellectual disabilities opportunities to participate in sports ranging from basketball and bowling to figure skating and gymnastics. Obama and first lady Michelle Obama will serve as honorary chairs of the Special Olympics World Games i
