President Barack Obama has spent more time traveling abroad than other U.S. president in history at this point in their presidencies, according to a forthcoming study from the National Taxpayer Union Foundation (NTUF) provided exclusively to Breitbart News ahead of its public release.

“The most internationally well-traveled President, through five years, is also flying the most expensive-to-operate Air Force One to date,” NTUF wrote.

After five years in the White House, Obama has taken 31 trips for a total of 119 days abroad. At that point in George W. Bush’s presidency, Bush had taken 28 trips for 116 days, while Bill Clinton had taken 27 trips for 113 days. Ronald Reagan, after five years, had taken 14 trips for 73 days while Richard Nixon had taken 12 trips for 60 days after five years in the White House and Lyndon Johnson took 10 trips for 34 days at the half-decade mark. Dwight Eisenhower took 8 trips for 31 days after five years in the White House.
