UPDATE: Robert Gibbs was asked about this at today's White House briefing. He explained that White House policy with regard to visitor logs has "been involved in litigation" for years, and that the new administration is "reviewing that policy."

"This is a president who underscored his commitment to transparency on this first full day in office," he said when asked if this review squared with the stated goal of the administration to be the most transparent. "

He later was asked about specific denials by the White House of requests for the logs from MSNBC and CREW.

"I think there are obviously occasions in which the president is going to meet privately with advisers on topics that are of great national importance," he said.

ORIGINAL POST:

MSNBC.com is reporting today that the Obama administration is fighting a request to release the list of White House visitors, "taking up the Bush administration argument that a president doesn't have to reveal who comes calling to influence policy decisions."

Despite President Barack Obama's pledge to introduce a new era of transparency to Washington, and despite two rulings by a federal judge that the records are public, the Secret Service has denied msnbc.com's request for the names of all White House visitors from Jan. 20 to the present. It also denied a narrower request by the nonpartisan watchdog group Citizens for Responsibility and Ethics in Washington, which sought logs of visits by executives of coal companies.

CREW says it will file a lawsuit Tuesday against the Department of Homeland Security, which oversees the Secret Service.
