If memory serves, Hazel O'Leary set records for spending taxpayers money on trips not only for herself, but her entire entourage.
Clinton took over 1,000 lackeys on jaunts to Africa and the Orient for no ostensible government purpose. This included Betty Currie at the same time that she was implicated in his Monica cover-up. This cost the taxpayers untold millions. The vision of this putrescence playing his bongo and smoking a cigar still haunts me.
