WELL, WHAT HE IS, IS SLIMY. Just Who Is Sidney Blumenthal, the Clintons’ Closest Advisor? Will Hillary’s hatchet man be up for White House job if she wins?

He’ll do for America what he did for Libya. Plus:

Sidney Blumenthal is all over the Benghazi affair. And Ms. Clinton’s long, strange, close relationship to this shadowy and increasingly untrusted figure might just keep her from winning the White House.

Last Friday, the State Department released emails showing that Mr. Blumenthal had reached out to Ms. Clinton on behalf of Jonathan Powell, ex-chief of staff to former British Prime Minister Tony Blair. Mr. Powell proposed establishing “below the radar” channels between insurgents and governments and making money off of it through an NGO of Mr. Powell’s. Ms. Clinton was receptive to the idea, according to the Daily Caller. When he was at The New Yorker, Mr. Blumenthal wrote an ass-kissing profile of Mr. Blair in which he called his subject, among other things, a man of “impeccable Oxford diction.”

Tina Brown, who hired Mr. Blumenthal at The New Yorker because he was close to the Clintons, later allegedly canned him for being too close to the Clintons.

To cite another striking example, Mr. Blumenthal sent then-Secretary of State Ms. Clinton reports on the political situation in Libya written by a former senior CIA officer, the recently deceased Tyler Drumheller. Those reports, which Mr. Blumenthal emailed to her in 2011 and 2012, apparently were intended to influence American policy toward Libya in a way favorable to a business project with which Mr. Blumenthal and Mr. Drumheller were involved.

Culture of corruption.
