So she illegally ran a private email server.
Actually, her use of a private email server was legal. The requirement that email servers for official government business must be on a government server was an amendment to the Federal Records Act that was passed in late 2014, *AFTER* Clinton had resigned as secretary of state. It's worth noting that previous Sec of States, including Colin Powell, also used private email servers (legally) for government business although the RNC-hosted services "lost" all of his emails so we'll never see what thoughts went into, say, the Iraq War Part 2.
Deleted requested emails after a subpoena for them.
She claims that she deleted only e-mails of a personal nature and handed over all of the "requested" emails. It's your word against hers.
Emailed classified information from an unsecure server to Sydney.
The information in question was classified at a later date. It was not classified at the time it was transmitted.
Lied to Congress about it.
Again, no proof of wrongdoing yet, unless you believe everything that Fox News is saying. So far there is only the fact that a couple of officials have asked to open an investigation.
Also, considering that there have been something like 55 investigations and hearings into Benghazi and not a single one of them has found any fault for Clinton, I'm going to take any "inquiry" requests with a grain of salt until there is an actual factual finding of wrongdoing.
