So who’s responsible for the Bill Richardson mess? Depends on whom you ask. Obama sources tell The Washington Post that Richardson was less than forthcoming on the grand jury probe into his gubernatorial office, downplaying its importance and failing to reveal that his office might be at risk. The New Mexico governor also failed to disclose the investigation a background-check questionnaire. But Richardson surrogates say he did nothing wrong and that the transition team knew all there was to know about the grand jury probe. If they failed to identify it as a problem, a senior Richardson aide said, that's their own fault. The probe is focused on David Rubin, a Richardson donor, who secured a lucrative state highway contract in New Mexico.
