Attorney General Loretta Lynch met privately with Bill Clinton in Phoenix, Ariz. Tuesday afternoon amid the federal government's ongoing probe into Hillary Clinton’s unsecured email server.

Lynch met with the former president for 30 minutes aboard a government-owned private jet at Sky Harbor International Airport, local network ABC15 reported.

Lynch, who will have the final legal authority on any indictments concerning Clinton and her former State Department aides, only confirmed the unannounced meeting after she was pressed by the Arizona news station.

Lynch said her conversation with the former president did not touch on government business.

"There was no discussion on any matter pending before the Department or any matter pending with any other body, there was no discussion of Benghazi, no discussion of State Department emails," she said at the Phoenix Police Department.

Clinton waited for Lynch at the airport after he was notified she would be arriving.

In March, the FBI completed its year-long investigation into Clinton’s private email server. Agency Director James Comey, who was joined by DOJ investigators during the probe, will make a recommendation to Lynch about whether to pursue criminal charges against Clinton or her aides.

Lynch, an Obama appointee, will be in charge of making the final decision on indictments.
