Holly Petraeus is stepping back into the Washington social scene later this month, attending PenFed Foundation's Night of Heroes Gala on May 23. Since news of David Petraeus' affair, Holly has continued to do work on behalf of military families as assistant director of servicemember affairs for the Consumer Financial Protection Bureau. This marks a more high-profile event, as Eric Shinseki, secretary of Veterans Affairs, and Sen. Elizabeth Warren, D-Mass, also will attend.
