(CBS) - Bill O'Reilly has already tackled the presidential assassination of Abraham Lincoln in his 2011 book, "Killing Lincoln." Now the Fox News host is taking on the death of John F. Kennedy in the soon-to-be-released book, "Killing Kennedy: The End of Camelot."

According to the Associated Press, O'Reilly says "Killing Kennedy" will "answer many questions" about the death of JFK, who was murdered on Nov. 22, 1963. The book is due out this fall.

"Killing Lincoln" was one of the best-selling books of 2011, with 1.5 million copies in print. O'Reilly will publish a children's version of "Lincoln's Last Days" in August.

O'Reilly appeared on NBC's "Today" show Thursday to discuss his upcoming book, but he mostly talked about recent comments he made about Whitney Houston.

Earlier this week, O'Reilly addressed the Houston's death on his show. "Whitney Houston wanted to kill herself ... the hard truth is that some people will always want to destroy themselves, and there's nothing society can do about," he said.

O'Reilly reiterated the controversial statements and blamed the media while speaking with host Matt Lauer, explaining, "I don't believe that anyone is a slave to addiction ... You have free will and you can get through the disease, as millions of people have chosen to do ... You don't have free will when you have lung cancer. You do have free will when you're a crack addict ... We, the media, looked the other way in the death of Whitney Houston. Everyone knew she was a drug addict for two decades."
