As it turns out not only did the Republicans already know that Hillary Clinton used a private e-mail service while Secretary of State, they have already read them.

Rep. Adam Schiff (D-CA) said, “We knew as of last summer that the Secretary used a private email account. This is not something new. We knew also that she was cooperating. She was giving us everything that we asked for. Nothing changed except for the pressure on the Republican members of the committee this week became too great for them to resist from the Stop Hillary PAC people and the RNC people, so they issued a subpoena for records that we already have. Now, the Secretary has called for those records to be made public. Why isn’t the chairman doing that? Why aren’t we doing that? The reason is we’ve read them. There’s nothing in them. My colleague says well, how do we know we have them all? The reality is that if this secretary or anyone else emailed a stand down order as this mythical claim exists out there, there would be several people on the receiving end of that email. There would be people at the Pentagon, people in the field who would have to receive that order. None of that. There is no evidence of that.” 

Rep. Schiff brought up a great point. If there were anything in the emails, Republicans would have quickly made the emails public in order to build and prolong the story. The fact that former Sec. Clinton has called for the emails to be released, but Republicans refuse to make them public, speaks volumes about what this “scandal” is really about. The subpoena for documents that they already had in their possession is straight out of the Republican Benghazi playbook.

You know this occurred to me when I first heard about his so-called "scandal" as well. 

There have been several investigations into the Benghazi incident, by a number of Republicans. Which means they would have seen that Clinton's e-mails were coming from a non-government e-mail address, and yet that did not seem to raise a red flag until just last week?

And by the way, just speaking for myself, whenever I see a debate on ANY topic that includes Darrel Issa taking the side of the Republicans, I immediately feel that they have lost the argument.

The guy is one of the biggest clowns in the GOP, and I swear that if he were trying to convince me that water was wet I would have a hard time believing him.
