ROCKVILLE - The Virginia couple at the center of last week's White House security breach is now accused of bouncing a nearly $24,000 check for liquor purchased in Maryland. The Montgomery County government, which conducts all the wholesale liquor sales on its territory, filed a lawsuit Thursday against Michaele and Tareq Salahi, the couple who got into a state dinner last week without an invitation. The Salahis purchased wine and beer for America's Polo Cup World Championship, a charity polo event they held in the county in May. According to documents, the couple returned more than $10,000 worth of merchandise, but they still owe more than $13,000.
