WASHINGTON (Reuters) - The Senate intelligence committee on Wednesday postponed until next week a vote on the confirmation of White House aide John Brennan to be CIA director, dashing hopes of Democratic leaders who had hoped to have a vote on Thursday. The committee's Republican vice chairman, Senator Saxby Chambliss of Georgia, said the panel expects to hold the vote on Tuesday. No explanation for the delay was immediately available. On Wednesday, administration officials met with intelligence committee members to discuss the contents of the disputed documents. Senator Ron Wyden of Oregon, a key committee Democrat who had indicated earlier his preference that the vote not be held until the administration made additional disclosures, said late on Wednesday he was still not satisfied with what the White House had provided. "Americans have a right to know when their government believes it is allowed to kill them, and that's what getting these documents" is about, Wyden said. "I've made it very clear to the White House that we need those legal analyses before we vote," Wyden said. But he added: "There is certainly additional time to work this out."
