WASHINGTON (November 16, 2012)--A Tampa Bay, Fla., socialite whose e-mails triggered the eventual downfall of CIA director David Petraeus, visited the White House three times this year with her sister, twice eating in the Executive Mansion mess, an administration official said.

The official said Jill Kelley, who initiated an investigation that ultimately unveiled Petraeus' extramarital affair, and her sister had two "courtesy" meals at the White House mess as guests of a mid-level White House aide.

Kelley and her family also received a White House tour.

The visits occurred during the past three months.

The official spoke on condition of anonymity because those visitor records have not yet been made public.

The official said the White House aide who hosted her met the Kelley family at MacDill Air Force Base near Tampa.
