Former First Lady Michelle Obama tweeted Sunday that she’s canceling two stops on her best-selling "Becoming" book tour in Paris and Berlin to attend the funeral of former President George H.W. Bush.
"It’s important to me to join the Bush family in celebrating President George H.W. Bush’s exemplary life. This will unfortunately preclude my visits to Paris and Berlin. I’ve been deeply touched by the enthusiasm for my memoir, and I’m working to reschedule my trip for next year."
The backdrop: The hardcover edition of "Becoming" has sold more copies than any other book in the U.S. this year, according to Penguin Random House — more than 2 million copies in the U.S. and Canada alone.
