In his first term as mayor, Rudy Giuliani appointed Brendan Sexton to head NYC's Procurement Policy Board, one of the little-known offices that, we now know, Giuliani used to hide the costs associated with his romantic, adulterous getaways.

And what does Sexton think now that he knows his office's budget was misused by his former boss? I'm glad you asked.

A former Giuliani administration official says he's "sick" over reports that his little-known agency was used to hide taxpayer money that funded police escorts during the ex-mayor's romantic rendezvous in the Hamptons.

"The cover-up of this and the explanations for it have been so disingenuous," said Brendan Sexton, who chaired the Procurement Policy Board in 2000. The panel was charged $29,757 for travel bills racked up by then-Mayor Rudy Giuliani's security detail as he hung out with then-girlfriend Judith Nathan on Long Island.

"He didn't want anybody to know what he was doing. That's the truth. I don't care about his personal life - it's not shocking to me that he wanted to visit his girlfriend," added Sexton, a Democrat who served as sanitation commissioner under Ed Koch.

"The part that's disturbing to me is that my organization or any government organization could be used to conceal from the public how their money was being spent."

Sexton added, "At first, I thought it was humorous. I just couldn't believe anybody would do this. After that, I was sort of sick about it."
