Today in the continuing saga of alleged White House state dinner crashers Tareq and Michaele Salahi...

Our colleagues Michael Shear and Spencer Hsu report that the unwanted incursion of the Northern Virginia socialites into the president's personal space last week is adding new urgency to an ongoing review of security; some predict the episode will lead to much intensified protection of the first family. A Secret Service veteran tells them the Social Secretary's office better "buy umbrellas before the next event because you can be sure the Secret Service will be doing their job, and it may be that visitors will be out there for a very long time."

Our colleague Wil Haygood presents a history of White House gatecrashers:

"They come through rain, sleet, snow, the cover of darkness, and the prettiest of days with sunshine touching them. They make headlines. They go down in history. And most certainly they have their mental capacity questioned."

From The Reliable Source's Amy Argetsinger, a comprehensive look at the "Real Housewives" invasion of Washington, D.C. -- how they picked their cast, how they brought the drama, and what the future holds now that Tareq and Michaele have turned into walking spoiler alerts. And from the editorial section, Anne Applebaum on the art of social-climbing.
