The Democratic Party mega-donor at the center of the scandal surrounding New Jersey Democratic Sen. Bob Menendez has now opted to hide his private jet’s flight path data from the public, Breitbart News has learned.

The flight tracking data for ophthalmologist Dr. Salomon Melgen’s private jet was publicly available from FlightAware until recently. Sometime in the past week, as the scandal heated up, Melgen opted to hide the data from the public.

Visitors to FlightAware’s website who search for data about Melgen’s jet—which bears the tail number “N900LG” and is owned by his company—are now blocked from accessing the information. The website says the reason why the data is not public anymore is because the jet’s owner requested it be hidden.

“This aircraft (N900LG) is not available for public tracking per request from the owner/operator,” the site reads.
