President Barack Obama momentarily batted back tears as he thanked his wife, Michelle, during the emotional tail-end of his farewell address in Chicago Tuesday."Michelle Lavaughn Robinson, girl of the South Side - for the past 25 years, you have not only been my wife, the mother of my children, you have been my best friend," Obama said. "You took on a job you didn`t ask for, and you made it your own with grace and with grit and with style and good humor."Obama at one point took out a white handkerchief to wipe his eyes. Malia, his eldest daughter, also was seen wiping away tears.The President`s speech centered on the threats to democracy but also his fundamental belief in the system, asking his supporters to still trust that change and progress are possible. He also gave a shout-out to his vice president, Joe Biden, calling him "a brother." "You made the White House a place that belonged to everybody," he said about Michelle Obama. "You have made me proud, and you have made the country proud."Shortly after his speech concluded, Michelle Obama tweeted a picture of a much-younger looking Obama family saying, "So proud of @POTUS and all that we`ve accomplished together. An incredible journey filled with remarkable people. I love you Barack. -mo."Source: CNN
