He lied and made himself a story for personal gain. Seems his lies have caught up with him.Williams, the most-watched network anchor in the US, often spoke of being shot down in a helicopter in Iraq.
However, after veterans disputed his account, he admitted getting the story wrong and blamed the "fog of memory".
Last week, he apologised on air for the lapse.
"I made a mistake in recalling the events of 12 years ago," he said. "I want to apologise. I said I was travelling in an aircraft that was hit by RPG [rocket-propelled grenade] fire. I was instead in a following aircraft."
NBC News President Deborah Turness said that Williams had "misrepresented" events from the Iraq war.
"It then became clear that on other occasions Brian had done the same while telling that story in other venues," Turness said.
"This was wrong and completely inappropriate for someone in Brian's position." Link.
