At an event in Bogalusa, Louisiana Saturday, Mary Landrieu took time out of her stump speech to get something “off my chest” about her $2.5 million D.C. mansion. ... Landrieu lives in a 7,316 square foot D.C. mansion with 5 bathrooms, 4 water heaters, 2 dishwashers, and 82 fire sprinkler heads. Meanwhile, Landrieu does not own any developed property in Louisiana and bunks with her parents on the occasions she visits the state.
