Bush daughters offer advice to Malia and Sasha Obama in open letter

"We have watched you grow from girls to impressive young women with grace and ease," wrote Barbara Bush and Jenna Bush Hager in an open letterĀ published by Time Magazine.

The Bush daughters -- who first became familiar with the White House during the presidency of their grandfather, George H.W. Bush -- recalled returning to the executive mansion in 2008 as young women to show the Obama girls around.
