"Donald Trump ought to fire him," Gore said in an interview on CNN's "The Van Jones' Show."

"It won't do him any good for me to say that," Gore added. "But if I told him to keep him on, maybe that would make him fire him."

Gore's comments come as Pruitt faces a series of controversies over issues ranging from his past living arrangements in a condo owned by the wife of a prominent energy lobbyist to his high travel and security expenses.

A growing number of lawmakers have called for the EPA chief's resignation in the face of the controversies. Pruitt has denied any wrongdoing.

Gore, a longtime environmental advocate who won the Nobel Peace Prize in 2007, told CNN that Pruitt's actions give the appearance of corruption within the government, and that most Americans likely see the scandals as problematic.

"I will tell you that I would be very surprised if 90 percent of the American people looking at that situation did not think that there was the appearance of outright corruption there," Gore said.

"Regardless of party, regardless of ideology or his policies, the American people have a right to believe there is some modicum of integrity in the way our government is operating," he added.
