Walter Isaacson leaving BBG, says he’s busy with ‘big writing project’

Walter Isaacson, who penned a best-selling book about the late Apple co-founder, Steve Jobs, resigned Friday as the chairman of the Broadcasting Board of Governors to work on another book.

“I'm taking on another big writing project, so I won't be able to give the BBG the time it needs and deserves,” he said in a resignation letter sent Friday to the agency, which oversees U.S. international broadcasting, including the Voice of America and Radio Free Europe.
