Melania Trump kicked off Day 2 of her Fostering the Future summit with a special guest -- a robot. The White House crowd burst into applause as the robot joined the first lady for a grand entrance. The humanoid figure kicked off the roundtable with brief remarks. “I'm Figure 3, a humanoid built in the United States of America. I am grateful to be part of this historic movement to empower children with technology and education,” it said. The First Lady thanked it for being there.
