Some viewers may have noticed that MSNBC “Morning Joe” co-host Joe Scarborough was noticeably absent on Monday. Well, as it happens, Scarborough called in sick at 5 a.m. Sources say he didn’t want to deal with any fallout from the news that leaked out in The Daily Caller Monday that he’s irking some of his colleagues with speaking engagements that appear to be in conflict with NBC rules. Ask Joe why he called in sick on Monday (he can be reached at @JoeNBC). What’s he avoiding? And what was his ailment? He certainly didn’t seem to have so much as a sniffle Tuesday morning.
