MSNBC's Joy Reid moved quickly to dispute a guest's suggestion that there are 33,000 State Department emails from Hillary Clinton's private server out there that could pose a threat to U.S. national security, and referred to the charge as an invented thing.

"You just invented an entire thing!" Reid told guest Amy Kremer, who formerly chaired the Tea Party Express.

"The FBI has already come out with a report on Hillary Clinton's emails. What you just said was an invented thing!" the cable news host added. "There's no 33,000 emails that are going to harm our national security."

Reid's remarks came as Kremer sought to defend GOP nominee Donald Trump, who suggested last week that the Russians should help the U.S. find Clinton's State Department emails.

"The servers are no longer hooked up and working. I mean If they are, they are with the FBI. And people know that they are not available to hack anymore," the former Tea Party chief said as she defended Trump from claims that he had encouraged the Russians to hack into Clinton's private servers.

"I mean, it's like Donald Trump saying, 'Oh, I hope Putin goes and gets in a 1985 DeLorean and goes and finds those 33,000 emails.' I mean it's absolutely ridiculous. I'll tell what you scares me," she added. "What scares me is the fact that the emails are out there somewhere, probably, and that we could have —"

"Hold on. You can't just invent things! You can't just invent things," Reid interjected. "You know that there was an entire year-and-half investigation! We're not going to re-litigate that!"

Clinton said in December 2014 that she turned over more than 30,000 emails to the State Department. However, she also said at the time that she deleted roughly 32,000 emails from her private servers.

The former secretary of state and her team argued they deleted nearly half of the emails on her private servers because the messages were personal, and that they didn't qualify as work-related.

Much of the FBI's investigation into Clinton's use of a private server focused on recovering those deleted emails.

FBI Director James Comey, who recommended no charges be brought against Clinton, said in July his investigators "discovered several thousand work-related" notes among the trove of thousands of deleted emails.

The FBI chief also revealed some of the deleted emails contained classified information, contrary to Clinton's earlier claims.

"From the group of 30,000 emails returned to the State Department, 110 emails in 52 email chains have been determined by the owning agency to contain classified information at the time they were sent or received," he said.

The FBI will send "several thousand" of the recovered emails to the State Department, which will make the once-deleted notes available on a "rolling basis," a government lawyer announced this month.

On MSNBC, Reid and Kremer argued over whether Clinton's emails actually pose a threat to U.S. national security.

"Nope! No! No, ma'am! No, ma'am!" the host said. "You cannot invent things."

"Yes! The FBI also said that she has not turn over — she didn't over all the emails," her guest said.

"No, ma'am! No, Ma'am! You cannot invent things. You cannot say things — You're putting out incredibly inflammatory information," Reid continued.
