Often, it is true: Where there’s smoke, there’s fire. In Hillary Clinton’s case, it is a four-alarm blaze.

More revelations about her improper use of a private email server while secretary of state came to light recently. The State Department’s own inspector general released an 83-page report detailing Clinton’s actions, which jeopardized national secrets.

In the report is evidence that despite her claims she was doing nothing wrong, steps were taken to cover up Clinton’s use of the private server. While she was secretary of state, an official there responded to staff members’ concerns about the server by telling them to “never speak of the secretary’s personal email system again.”

Smoke is billowing out of Clinton’s tenure as secretary of state. Why has the Justice Department dragged its feet in bringing charges against her? Could politics be involved?
