Former President George W. Bush launched his book tour, Tuesday, with a signing near his home in Dallas.

Bush's memoir, titled Decision Points, outlines the critical choices he had to make through his presidency and personal life.

Dr. Charles Dunn, dean of Regent University's School of Government, discussed how far the memoir will go to redefine the Bush legacy on the Nov. 10 edition of CBN Newschannel's Morning News. Click play to watch the interview.

In an interview with NBC's Matt Lauer, Bush shared an experience involving a miscarriage his mother had.

"[There's] no question it affected me, my philosophy that we should respect life," Bush said. "I was a pro-life president."

In the book, the former president also discusses his deliverance from alcoholism. He said his Christian faith helped him quit "cold turkey."

When asked if he ever fell off the wagon during the stressful times of his presidency, Bush responded, "No. Of course not."

"I haven't had a sip of alcohol since 1986," he added.

Decision Points includes Bush's thoughts on the Sept. 11 attacks, his decision to send troops to Afghanistan and Iraq, and his response to Hurricane Katrina.
