I seriously hope not. Once it was proven that he'd stretched the truth, lied and in at least one case, completely fabricated stories about places he'd supposedly been, things he'd done, etc. he lost any and all credibility as a journalist and newsman. it also sets up any network who hires him in the future for very easy attacks from the right. All they need to say is "XYZ network spits out the same lies as the rest of the mainstream media. Don't believe us? They hired Brian Williams, the biggest fabricator of them all....Roll the tape."
