Both trips included campaign-related events that raise questions about whether some or all of the costs of the charter flights should have been covered by Landrieu’s reelection campaign, rather than her official office. The trips are becoming a serious headache for Landrieu, who is in the fight of her political life this year against Rep. Bill Cassidy (R-La.). After other reports of improper travel spending, Louisiana Republicans are dubbing Landrieu “Air Mary” to portray her as out of touch with voters after her lengthy Senate career. The key will be determining whether the trips in question were mostly fundraising swings — not official travel. Landrieu has ordered her staff to look into the matter by the end of the month.
