A Republican member of the House Intelligence Committee said Wednesday that the State Department has classified seven more of Hillary Clinton's private emails as "top secret."

"There are more than 22, and it's not just one or two more," Rep. Chris Stewart told the Washington Examiner, referring to the 22 emails deemed top secret by the State Department last week. "It's a more meaningful number than that."

Stewart said the State Department has classified seven additional emails as "top secret." The agency will now withhold 29 emails from the public due to their sensitive content.

"These were classified at the top secret level, and in some cases, above that," he said.

Stewart said his years of experience handling highly classified material allowed him to recognize immediately the sensitive nature of Clinton's emails. The Utah Republican said he had never seen anything more sensitive than the information contained within the emails.

"They do reveal classified methods, they do reveal classified sources, and they do reveal human assets," he said during an appearance on Fox's "America's Newsroom" earlier in the day.

The State Department's decision on Friday to withhold 22 emails entirely, rather than redact only the sensitive portions, marked a departure from the agency's approach to the more than 1,300 emails that have been classified over the past eight months.

Clinton has attempted to downplay the move as a result of bureaucratic infighting. But the discovery of the highly classified messages has fueled speculation that the former secretary of state may be facing more serious legal trouble than previously thought.

John Kirby, spokesman for the State Department, declined to address questions about the additional top secret emails Wednesday.

"I don't have any additional emails to talk about in addition to the ones we've already very publicly talked about," Kirby said. "There's more emails we still need to release through the Freedom of Information Act. The work of reviewing and preparing these remaining emails is ongoing."
