President Obama’s advisers attacked critics for suggesting the White House fudged jobs figures, comparing them to “lunatic” birthers. The sub-8% unemployment stats were released by the non-partisan Bureau of Labor Statistics Friday, but former GE chief Jack Welch and several Tea Party figures claimed the numbers were cooked. Obama campaign senior adviser Robert Gibbs called such comments “incredibly dangerous” and said Welch had embarrassed himself. “There's a number of people that believe the real unemployment report is somewhere in a safe in Nairobi with the president's Kenyan birth certificate," Gibbs said sarcastically on NBC’s “Meet the Press” Sunday.
