Tampa socialite and military booster Jill Kelley and her sister Natalie Khawam - figures at the center of the David Petraeus scandal - were cleared into the White House complex three times this year, most recently last week, for what are described as tourist visits facilitated by a mid-level White House staffer.

On Nov. 4, just two days before the election, Kelley, her husband Scott, and three children, plus Khawam and her child, all visited the White House for a tour hosted by the staffer, an administration official told ABC News.

The sisters first visited on Sept. 28, joining the staffer for breakfast in the White House mess. On Oct. 24, the duo made a second visit for lunch with the staffer in the mess, the official said.

Neither Kelley nor Khawam met with the President or any other senior administration officials on their visits, sources said. They were present only for a "tour" and "courtesy meals." (President Obama and his senior aides were out of Washington, barnstorming the battleground states on Oct. 24 and Nov. 4.)

Officials declined to reveal the identity of the staffer, citing privacy concerns. However, his or her name will be revealed publicly in less than 90 days when White House visitor logs for those dates are posted online.

Petraeus biographer and paramour Paula Broadwell was also on the White House campus twice during President Obama's first term - on both occasions for meetings in the Eisenhower Executive Office Building.

In June 2009, she met with a national security staffer who handled Afghanistan and Pakistan policy. Two years later, in June 2011, she attended a broad briefing on Afghanistan-Pakistan policy for a group of approximately 20 attendees, an administration official said.

Neither meeting is reflected in White House visitor logs posted online.

An official explains that Broadwell's first visit in 2009 predated the administration's voluntary disclosure policy, meaning the system of posting digital records had not yet been initiated. The second meeting was withheld from the disclosures under the national security exemption of the disclosure policy, one source said.
