Sen. Mary Landrieu, a Louisiana Democrat in the midst of a close re-election campaign, is under fire from her main Republican challenger for listing her parents' house in New Orleans as her home address in election filings.
Landrieu, a three-term incumbent, is a top target of Republicans in their quest to reclaim the U.S. Senate from Democrats.
The senator, who shares a Washington D.C. house with her husband, said that her parents' home, where she grew up, remains her primary Louisiana residence.
"I have lived at my home on Prieur Street most of my life and I live there now, when not fulfilling my duties in Washington or serving constituents across the state," Landrieu said in a statement.
The New Orleans house, in the middle class Broadmoor neighborhood, has been her parents' home for decades. Her brother, New Orleans Mayor Mitch Landrieu, lives nearby.
Moon Landrieu, the senator's father, is a former New Orleans mayor.
U.S. Representative Bill Cassidy, a Baton Rouge-area Republican seeking to unseat Landrieu, criticized her as not being a true resident of Louisiana.
"Senator Landrieu belongs in Washington, D.C. She just chooses Louisiana to get reelected," Cassidy said on Twitter. (Reporting by Jonathan Kaminsky; Editing by Cynthia Johnston and Sandra Maler)
