Taxpayers spent more than $4 million over the last four years on Attorney General Eric Holder’s travel costs, according to a new report.

Judicial Watch, a conservative watchdog group, says it determined those figures detailing Holder’s travel costs from March of 2009 to August 2012 through a Freedom of Information Act request.

The group deemed $697,525.20 of those expenses as “taxpayer-funded personal travel expenses.”

Judicial Watch did not compare those figures to other attorneys general. But the president of the group blasted Holder, who uses government aircraft for security reasons.
