(CNN) -- Jack Welch, the former chief executive of General Electric, was unhappy that the Labor Department reported a 0.3 percentage point decline in the unemployment rate on Friday. In fact, he was sufficiently unhappy that he accused the Obama administration of using its control over the Labor Department to cook the numbers in a tweet just after the unemployment rate was reported. He even repeated the claim in a Wall Street Journal opinion piece on Wednesday.

Perhaps Welch could get away with this sort of temper tantrum nonsense when he was running one of the biggest companies in the world, but he will only get ridicule pushing this line in policy debates. Either Welch doesn't have any clue about how the unemployment data are collected, or he is just a liar.
