6. Linda Tripp
Perhaps the most famous whistleblower of all, White House staffer Linda Tripp went public in 1998 with information about President Clinton’s extramarital affair with intern Monica Lewinsky.
After at first denying the claims of wrongdoing, Clinton became the second ever U.S. president to be impeached after being found to have lied under oath and attempting to obstruct the course of justice.
For her troubles, Tripp experienced various forms of retaliation from the Clinton Administration. She received a cash settlement in 2003, as well as pension rights and clearance to work again for the federal government.
