Top Secret Emails Sent on Clinton's Private Server

A federal investigation of Hillary Clinton now shows two emails on her private server were classified as "top secret." The revelation is causing a deepening campaign crisis for the presidential candidate.

The new information of Clinton's official use of personal emails came from the intelligence community's inspector general. The I.G. notified members of Congress that two of the four classified emails found on Mrs. Clinton's private server were listed as "top secret."

Clinton's campaign said it will turn over her server to the Department of Justice. The FBI is already investigating whether the former secretary of state sent or received classified government information on an unsecured system.

Members of the U.S. Congress have been pushing the Department of State and Mrs. Clinton for details of more than 50,000 emails kept on a private server at the Clintons' New York home. Clinton has already admitted to deleting as many as 30,000 email messages -- and she still insists none of her emails were classified when she sent them.

But she was using a private, not a government, email server. And there's no evidence that she was using encryption to prevent her emails from being spied upon.

Even government computers -- let alone private ones -- are susceptible to spying.

Current Secretary of State John Kerry admits recent hacks of U.S. government computers suggest the Chinese and Russians are "very likely" reading his emails.

Meanwhile, the email investigation is damaging Clinton's popularity nationwide and especially in Iowa -- a state President Barack Obama carried in the last presidential election.

While she leads among Democrats, a recent Public Policy Poll (PPP) shows Hillary now losing to four Republican candidates in Iowa -- Florida Sen. Marco Rubio, Wisconsin Gov. Scott Walker, retired neurosurgeon Ben Carson, and former Arkansas Gov. Mike Huckabee.

And it isn't just the private email server issue that's causing her to lose public support and trust. Instead of blasting one another, some of the Republican presidential candidates are now targeting Mrs. Clinton's record as secretary of state.

Former Florida Gov. Jeb Bush says the Islamic State grew as the United States disengaged from the Middle East. He blames the president along with Hillary Clinton.

"And where was the secretary of state? Where was Secretary of State Clinton in all of this?" Bush asked. "Like the president himself, she had opposed the surge and then joined in claiming credit for its success and then stood by as that hard-won victory by American and allied forces was thrown away. In all her record-setting travels, she stopped by Iraq exactly once."

With the Iowa caucuses half a year away, there is still plenty of time for Clinton to recover from her dropping poll numbers. But her political future may depend on what else turns up in the email investigation.
