Holder says contempt citation unwarranted COPENHAGEN (Reuters) - Attorney General Eric Holder on Thursday dismissed as unwarranted a vote by a congressional committee to charge him with contempt of Congress after the Obama administration withheld documents related to a failed gun-running investigation. "The action that the committee took yesterday was unwarranted, unnecessary and unprecedented," he said after meeting European Union justice officials in the Danish capital. The contempt move comes after the Obama administration asserted executive privilege as its reason for withholding some of the documents requested by the Republican-controlled House of Representatives' Oversight and Government Reform Committee. It set up yet another confrontation between Democratic President Barack Obama and the House, intensifying the bitter partisanship that has prevailed in Washington since just after Obama took office. The botched operation was meant to help law enforcement agents follow the flow of guns from Arizona into Mexico, but they lost track of many of the weapons, which later were involved in crimes. Holder told a news conference he remained optimistic the conflict with the committee could still be resolved on the basis of the administration's proposal. "We put before the committee a proposal that would have allowed for the resolution of that matter consistent with the way in which these have been resolved in the past, through negotiation," he said. "I think that the possibility still exists that it can happen in that way," he said. The House leadership has to consider now what they will do, so we'll see how it works out.
