"Some Congress members were caught deeply absorbed in their phones during the State of the Union Address as Donald Trump laid out his plans for revitalizing the American economy. One was caught playing a video game.
Brenda Lawrence, Democratic Representative for Michigan, was caught playing ‘Candy Crush’, a popular iPhone game, during the president’s first State of the Union Address. Could this explain why so few Democrats applauded Trump as he announced his first-year achievements inside the Capitol?
In the revealing photograph, reportedly snapped by Chip Somodevilla of Getty Images, Lawrence is seated alongside Bonnie Watson Coleman and Joyce Beatty, Democratic representatives from New Jersey and Ohio, respectively.
