According to the Gingrich-authored blog post Gingrich was promoting with his tweet, CBO is “a left-wing, corrupt, bureaucratic defender of big government and liberalism.” Later in that same post, Gingrich said CBO was “obsolete, inaccurate, and dishonest. That's pure political tripe (my editors would never let me use what I consider the most accurate description for what Gingrich said). It also has notoriously and repeatedly demonstrated its incompetence with government shutdowns, including two while Gingrich was speaker. Gingrich, who was House minority whip at the time, was one of the Republicans leading that standing ovation. Several of his Republican House colleagues noted at the time that CBO was agreeing with the GOP that the Clinton proposal would be a government rather than a market-driven solution.
