Given Obama’s close relationship with the younger Bush, we’re not surprised that she canceled some of her upcoming book tour in order to attend his father’s funeral.

“It’s important to me to join the Bush family in celebrating President George H.W. Bush’s exemplary life,” she tweeted. “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.”

She continued, writing, “I hope readers and ticket holders will understand my decision regarding my desire to attend President Bush’s funeral, and join me in paying tribute to him and his tremendous contribution to our world.”
