Democrats sued the Secret Service on Monday for copies of White House logs to determine how often allies and associates of convicted lobbyist Jack Abramoff visited the Executive Mansion.

The Democratic National Committee filed the lawsuit in U.S. District Court in Washington, saying the Secret Service has failed to comply with a Freedom of Information Act request for the logs.

The Democrats want to know about White House visits by conservative activist Grover Norquist and Ralph Reed, a GOP candidate for lieutenant governor of Georgia.

They also are asking for logs that show visits by three former Abramoff business associates: Michael Scanlon, who has pleaded guilty in the corruption scandal; David Safavian, the former Bush administration who is under indictment in connection with Abramoff; and Patrick Pizzella, an assistant secretary of labor.

The Democrats filed the suit "to compel the Bush administration to stop the stonewalling and finally be forthcoming with details regarding the White House's level of involvement in the Abramoff scandal," Democratic National Committee Chairman Howard Dean said.

The Secret Service has agreed to provide the logs of Abramoff's visits to the conservative watchdog group Judicial Watch and the Democrats by Wednesday.

The agency did not immediately comment on the new lawsuit.
