Fox News host Sean Hannity on Wednesday night instructed conservative commentator Tomi Lahren, who was making her debut as a contributor for the network, to "go after" Fox News correspondent Geraldo Rivera over the importance of Hillary Clinton's email scandal.

Hannity began the segment by discussing how the FBI this week rejected a Freedom of Information Act request to release files about the bureau's investigation into Clinton's private email server during her tenure as secretary of state, citing a lack of public interest in the matter.

"How would this not be in our best interest? It's in everybody's best interest to get the truth, right?" Hannity asked.

Lahren agreed with Hannity and said it is funny that Clinton's privacy somehow trumps the public's right to know what was in her emails.

"When you use a private email on a private server, your privacy rights are out the window when you're the secretary of state of the United States of America," Lahren said. "You don't have privacy anymore! She chose to do this. This is on her."

Rivera disagreed with Lahren and pushed back, saying it is a "disaster" for Republicans to continue talking about Clinton's emails.

"I think that this is a disaster for Republicans to get anywhere near this stuff that has already destroyed the career of [former Rep.] Jason Chaffetz [R., Ariz.], who led the charge," Rivera said.

"It didn't destroy his career," Hannity interrupted. "He's at Fox!"

Rivera went on to say that Chaffetz and Rep. Trey Gowdy (R., S.C.) were "made fools of" during the investigations into her emails.

Hannity pushed back and asked whether Rivera was suggesting that American should ignore the law and whether he was calling for a two-tier justice system.

"Tomi, seat this guy out," Hannity said. "Tomi, jump—you go after Geraldo. Take him on. We need you here."

"I have some friends that spent a few hours in Benghazi who would really like to know what's in those emails and they would really like to know why she deleted them," Lahren said. "To say that that the public doesn't have a right to know or that we're not interested—that's a load of crap."

Lahren went on to say that she will "stay on" the Clinton email scandal until the "mainstream media stops covering Russia day in and day out."
