An investigation into official flight records of financier and convicted pedophile Jeffrey Epstein’s “Lolita Express” are once again dragging former President Bill Clinton into the national spotlight.

Flight logs obtained by Gawker in January 2015 put Mr. Clinton on the billionaire’s infamous jet more than a dozen times — sometimes with a woman whom federal prosecutors suspect of procuring underage sex victims for Mr. Epstein. Fox News reported Friday that records show Mr. Clinton declined Secret Service protection on at least five flights.

The network’s investigation reveals Mr. Clinton flew on the Boeing 727 “Lolita Express” 26 times, more than doubling the previously reported 11 trips.

“Bill Clinton … associated with a man like Jeffrey Epstein, who everyone in New York, certainly within his inner circles, knew was a pedophile. Why would a former president associate with a man like that?” said Conchita Sarnoff of the Washington, D.C.-based nonprofit Alliance to Rescue Victims of Trafficking, Fox reported. Ms. Sarnoff also authored a book on Mr. Epstein titled “TrafficKing.”
