From Ted McLaughlin at jobsanger:
It’s no secret that the Republicans, especially those in Congress, hate Hillary Clinton. They have been trying to bring her down for over a quarter of a century now. And since she started her campaign for the presidency, their hate has turned into terror. They know they have little chance to beat her this November (particularly since they nominated Trump as their candidate), so they are pulling out all the stops in an effort to make her look bad.
They have had committee after committee investigate her over the Benghazi tragedy. That culminated in an 11 hour grilling of Clinton before a House committee — a grilling that showed them up a desperate hypocrites, and made Clinton look better than ever.
Then they repeated that with investigations of her use of a private e-mail server while Secretary of State.
