Former first daughters Barbara Bush and Jenna Bush Hager wrote a touching letter to Malia and Sasha Obama as the teens’ father, President Barack Obama, prepares to leave office after eight years. the Bushes wrote. "But you have so much to look forward to. You will be writing the story of your lives, beyond the shadow of your famous parents, yet you will always carry with you the experiences of the past eight years." "You have lived through the unbelievable pressure of the White House. You have listened to harsh criticism of your parents by people who had never even met them. You stood by as your precious parents were reduced to headlines. Your parents, who put you first and who not only showed you but gave you the world."
