In the wake of a bombshell report that he fabricated a story about his acceptance into the U.S. Military Academy at West Point, Dr. Ben Carson appeared on "The O'Reilly Factor."

Carson explained that he excelled as an ROTC student in Detroit and was told that he could easily be accepted in the prestigious military academy.

He said he probably could have better clarified in his book that he never formally applied or was accepted.

"I told it as I understood it," Carson said.

As for recent accusations in the media that he fabricated parts of his compelling life story - including that he had a "pathological temper" as a young man, almost stabbed a close relative and nearly hit his mother with a hammer - Carson stood by his claims.

O'Reilly said he's going to take Carson at his word, asking, "You're not going to let me down, are you?"

"Of course not," Carson said. "Lying, I believe, is a grave sin, and there's just no way I would be sitting here lying about something like this."
