Dr. Phil says, like the rest of America, he was moved by the 9/11 memorial, which was just unveiled at the site of the World Trade Center.
He's also speaking out about his highly anticipated interview with George and Cindy Anthony, which airs Tuesday, September 13th and Wednesday, September 14th.
"What's your takeaway sitting down with George and Cindy Anthony for the first time?" asked INSIDE EDITION's Paul Boyd.
Dr. Phil said, "If you like the Anthonys or you vilify the Anthonys, I predict that your view may well change after you hear this interview."
It's the first time George and Cindy Anthony have been put on the hot seat since their daughter Casey was found not guilty of murdering their granddaughter Caylee.
Dr. Phil, who is a grandfather himself, became passionate when Boyd asked him about confronting the Anthonys over why it took them 31 days to report little Caylee missing to police.
"If I went 31 days and never heard a peep, a cry, a voice in the background while I was talking to my son or my daughter-in-law, warning bells would go off in my head," he said.
