Obama aide slams Clinton on secrecy

As the Democratic presidential contest heats up, Sen. Barack Obama’s campaign has begun escalating attacks on Sen. Hillary Clinton’s record on transparency in government.

On Wednesday, Obama campaign manager David Plouffe called the former first lady the "most secretive politician in America today."

"I think that you know Sen. Clinton has talked a lot about disclosure in the last few days,” Plouffe told reporters. “Sen. Clinton is the most secretive politician in America today. This has been a pattern throughout her career of the lack of disclosure.”

Meanwhile, on Monday the National Archives announced that it plans to release all of Sen. Clinton’s schedules from her time in the White House later this month but is asking that the judge delay the release of her telephone logs for at least one to two years.

Clinton has faced increasing criticism for not releasing the documents sooner.
