Just one day after losing it on-air, Bill O'Reilly apologizes to Alan Colmes for his fiery outburst. INSIDE EDITION has the latest.

Bill O'Reilly said he's sorry for his jaw-dropping on-air meltdown.

The Fox News host went ballistic on guest Alan Colmes Tuesday night over President Obama's position on the budget cut controversy.

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.
