Judicial Watch tracks costs related to presidential trips, including what it costs to operate Air Force One.

Three trips earlier this year – a Palm Springs golf trip in June, a trip to New York in July and a visit to Martha's Vineyard in August – cost the U.S. $3.1 million in travel expenses alone. It costs about $206,000 per hour to operate the president's private plane.

Last year's Obama family Christmas trip cost $3.7 million in flight expenses alone, with 17.8 hours in the air round-trip. Housing and security costs are on top of that amount but not all that information is released to the public.

Those expenses don't sit well with everyone.
