Washington Post conservative columnist Jennifer Rubin has no patience for people who dismiss the Benghazi scandal as a “vast right-wing conspiracy” — especially if those same people supposedly rely on talking points from Media Matters, the ultra-liberal George Soros-funded advocacy group.

Rubin and Current TV’s David Shuster on CNN’s “Reliable Sources” got into a bit of a heated back-and-forth Sunday morning after Shuster suggested that the White House’s Benghazi email dump last week proves that Republicans and journalists, most especially ABC News’ Jonathan Karl, were wrong to have insisted that the administration has been hiding something.

Rubin explained that Karl’s attribution was incorrect but that his story was, for the most part, correct.

Shuster disagreed.

“It was wrong,” the Current TV journalist said. “Because the overall Republican point here was that the Obama administration was trying to protect the State Department — the Obama administration was trying to protect the State Department — and that the White House was somehow trying to characterize the talking points or change the talking points in order to minimize political damage. That Republican idea is just flat out wrong!”

“Very nice to have the Media Matters talking points recited out of David’s lips,” Rubin shot back.

“What are you talking about?” Shuster asked. “I haven’t talked to anybody from Media Matters.”

Shuster continued, prompting Rubin to turn to Howard Kurtz, the show’s host, and say, “Howard, if you want to hear me that’s fine, if you don’t, you should mute him.”
