Former US president Bill Clinton's foundation has spent more than 50 million dollars on travel expenses since 2003.
An analysis of the nonprofit's tax forms has revealed that the spending includes 4.2 million dollars in 2011 for the William J. Clinton Foundation.
The analysis revealed that the foundation also spent 730,000 dollars for the Clinton Global Health Initiative and 7.2 million dollars for the Clinton Health Action Initiative (CHAI).
Businessman and Republican New York City mayoral candidate John Catsimatidis has lent aircraft to Clinton and to the foundation multiple times for travel, New York Post reports.
The travel includes Clinton's recent trip to Africa with daughter Chelsea.
According to the report, Clinton sometimes uses Catsimatidis' Boeing 727, while opting on other trips to use a smaller Gulfstream jet.
