Sam Stein of HuffPo reports:

Republican presidential candidate Rudy Giuliani acted improperly and appeared to be covering something up when he charged the cost of his and his girlfriend's security detail to obscure New York City agencies, former mayor Ed Koch told the Huffington Post.

. . . "There is something improper about charging costs to a department other than the NYPD," said Koch. "They are the ones who are supposed to pick him up no matter where he is whether or not it's in the city."

Koch, who served as the mayor of New York City from 1978 to 1989, said that the episode gave off the appearance that Giuliani, who was at the time married to his second wife Donna Hanover, was trying to hide his affair. He also suggested that Judith Nathan received her own personal protection, which would have been, according to Koch, a flagrant misuse of taxpayer money.

"I found it strange that his lady friend was given protection," said the long-time New York politico. "That was bizarre. She's not the city's responsibility. Rudy is the city's responsibility. Your wife and his children get protection, and that's understood. But certainly not your lady friend."

Government funded trysts.
