Lester Holt got a big promotion this week, though likely not in the way he hoped it would happen.Holt, a well-known figure on NBC News for the past 15 years, will temporarily replace Brian Williams as anchor of the "NBC Nightly News." On Tuesday, Williams was suspended for six months without pay, after executives discovered he misrepresented details of his reporting over the years.
