Video: Fox News Guest Attacks Hillary Clinton—'She Won't Go Away, She's Like Herpes'

Fox News correspondent Rick Leventhal had to apologize to the network's viewers on Thursday after a guest compared Hillary Clinton to herpes, a sexually transmitted infection.

The panel were discussing a call by President Donald Trump's lawyer Rudy Giuliani for yet another investigation into former Secretary of State Clinton's use of a private server for official emails. President Donald Trump reportedly wants the Justice Department to prosecute Clinton.

"I'm just amazed that with everything going on in the world, we still have Hillary Clinton in the headlines," Leventhal said.

"She won't go away," said Anna Paulina, director of Spanish engagement at Turning Point USA, a right-wing youth organization, one of the panellists on Fox News. "She's like herpes."

Leventhal was taken aback and appeared unsure how to deal with what was said.

"OK, that's news that we're breaking here. Er, not appropriate," Leventhal said before trying to move the discussion on to the migrant caravan heading up through central America to the U.S. border.

Paulina then disappeared from the segment.

After hearing views from the other panel guest, the Democratic political consultant Doug Schoen, who worked for President Bill Clinton, Leventhal apologized on behalf of Fox.

"We're going to wrap this segment a little early, Doug, because [of] some of the language that was used in this segment. We apologize to our viewers for that."

Then, when Fox News anchor Arthel Neville took over, she reiterated that apology.

"We all are all-Americans and that is the focus, and we want to reiterate that we do not condone the language that Anna Paulina just displayed here, and we apologize to Secretary Clinton for that. Fox News does not condone her sentiments...It's Thanksgiving guys, lighten up. Come on!"

Shortly before the 2016 election, then-F.B.I. Director James Comey said at the conclusion of an investigation into Clinton's use of a private server in her home for official emails that no criminal case would be brought against her.

But he did say she and her aides were "extremely careless" because some of the tens of thousands of emails sent over the server contained classified information.

Some personal emails sent before 2014 were deleted. Comey said there was no evidence of a cover-up.

Trump made Clinton's emails a focal point of his successful 2016 presidential campaign against her, referring to the Democratic candidate as "Crooked Hillary" and encouraging supporters to chant "lock her up" at rallies, which they still do more than two years on from his victory.
