"New Mexico Gov. Bill Richardson, Obama's choice for commerce secretary, withdrawing under pressure of a federal investigation into how his political donors landed a lucrative transportation contract. . . . A senior Obama adviser said Richardson gave assurances before he was nominated last month he would come out fine in the investigation. But as the grand jury pursued the case, it became clear that confirmation hearings would be delayed at least six weeks until the investigation was complete, said the adviser, speaking on condition of anonymity about the discussions because they were private. Aides to both men insisted Richardson made the decision to withdraw and was not pushed out by Obama. But one Democrat involved in discussions over the matter said transition officials became increasingly nervous during the last couple of weeks that the investigation could become an embarrassment to Obama, who ran on a clean government pledge."
Richardson accepted high level appointments and campaign assistance from Bill Clinton. Then, he refused to endorse, and ran against, Hillary Clinton for the Democratic nomination. Next, he lied to Bill Clinton about his intent to endorse in the primary race. Finally, he lobbied against Hillary Clinton's appointment as Secretary of State (he wanted the job). Ultimately, he was appointed Secretary of Commerce after giving assurances that he was clean.
This is what happens when you trust an ingrate and a backstabber.
