Former Florida Governor and U.S. Senator Bob Graham says most people don't know the whole story behind 9/11.
On Monday, Graham embarked on a book tour to promote his new novel "Keys to the Kingdom." The book is about Saudi Arabia's involvement in the September 11th attacks. Graham had to get clearance from the CIA to release his book, which he spent five years writing. Graham says the book merges fact and fiction.
"It's fiction, but I would say that 35 to 40 percent of it is pure fact except I changed the names of living people. Another 20 percent is based on fact that is exaggerated and the rest of it is fiction," said Graham.
Graham chaired the Senate Intelligence Committee during the 9/11 attacks and opposed the U.S. invasion of Iraq.
