The William J. Clinton Foundation has reportedly spent more than $50 million on travel expenses since 2003, according to an internal audit by the foundation's accountants.
The travel costs include paying for actress Natalie Portman to fly first class with her dog to a foundation event, notes the New York Post.
However, the foundation is a global entity, which would account for the high travel bill.
The foundation itself spent $4.2 million on travel in 2011, the Clinton Global Health Initiative rang up $730,000 and the Clinton Health Action Initiative (CHAI) dished out $7.2 million.
Businessman John Catsimatitis has loaned aircraft to former President Clinton and the foundation multiple times.
“I don’t think it’s necessarily their go-to plane, because the 727 is a pretty big plane," said a Catsimatitis spokesman said in a statement. "It all depends where they’re going and what they’re doing.”
Sometimes Clinton uses the plane at a discount rate and sometimes Catsimatitis donates the flight time.
Clinton's trips accounted for 13 percent of the 2010 travel budget and 10 percent of the 2011 travel budget.
Clinton wrote on his foundation’s website:
Essentially, the review said we needed stronger management staff full-time in New York, where most of our U.S.-based staff are located, and a larger, more independent board. We currently have 2,100 staff and volunteers in a total of 36 countries. The review told us that my passion to keep overhead costs down — at about a low 8 percent for most of the last decade, rising only to above 11 percent in 2012 as we invested to support our growth — had gone on too long and that the foundation needed better coordination without dampening the entrepreneurial spirit that infuses all our initiatives.
