Bill O'Reilly said he's sorry for his jaw-dropping on-air meltdown.
On his show 24 hours later, he apologized to Colmes, saying, "Even though I'm sorry I said Alan was lying, I should not have used that word. I'm glad the exposition occurred."
O'Reilly said he's not sorry for blasting the president.
"That's the reason I raised my voice last night, to get everyone's attention. I think I succeeded," he said.
