Hillary Clinton is coming under scrutiny for serial fiascoes that occurred while she was Secretary of State. It’s about time.

These are among the decisions that Hillary made, or at least presided over, that are emerging as real liabilities – for the country, as well as for her future presidential prospects:

Such policy malpractice – or outright malfeasance – has already cost four Americans their lives and may lead to the loss of many more.

For that reason, the new House Select Committee on Benghazi must focus on the nature and consequences of Hillary Clinton’s conduct with respect to the policies that led up to the attacks of September 11, 2012; what transpired that evening; and the cover-up that followed. To really get to the bottom of these matters, however, Chairman Trey Gowdy and his colleagues must also examine with care the role played by a top Clinton lieutenant who has, to date, been almost completely unmentioned in the reporting, leaking, and congressional inquiries about Benghazigate: Huma Abedin.

This is all the more curious since Ms. Abedin (pictured, above) has extensive family and personal ties to the Muslim Brotherhood. (See Andy McCarthy’s rigorous analysis of those ties here.)

The question is this: How many of the dubious decisions involving U.S. policy in the Middle East, especially the aforementioned ones – pursuant to which the goals of the Muslim Brotherhood and other Islamists were consistently advanced – were influenced by a woman long associated with the world’s preeminent jihadist organization sworn to our destruction?

A similar question was formally posed nearly two years ago by Reps. Michele Bachmann (R-MN), Louie Gohmert (R-TX), Trent Franks (R-AZ), Lynn Westmoreland (R-GA) (a member of the Gowdy select committee), and Tom Rooney (R-FL) in a letter to the Inspector General of the Department of State. They requested that the IG conduct “a formal investigation or evaluation of the extent to which Muslim Brotherhood-tied individuals and entities have helped achieved the adoption of [several enumerated] State Department actions and policies, or are involved in their execution.”

Rep. Bachmann was personally savaged by Senator John McCain and others for having raised such perfectly legitimate questions. Ever since there has been little evident appetite – on Capitol Hill, in the media, or elsewhere – to pursue them and where they lead.

But now, the select committee has a mandate to get to the bottom of the Benghazigate scandal. If Rep. Gowdy and Company are to do so, they must examine with care the decisions about “State Department actions and policies” that led inexorably to that murderous attack – and that have the potential to threaten many more of us unless corrected. And doing that will require the select committee to establish precisely who the decision makers were and ensure that they are held accountable at last.
