The day after the Sept. 11, 2012, attacks on American outposts in Benghazi that killed Mr. Stevens and three other Americans, Mr. Blumenthal sent Mrs. Clinton a memo with his intelligence about what had occurred. The memo said the attacks were by "demonstrators" who "were inspired by what many devout Libyan viewed as a sacrilegious internet video on the prophet Mohammed originating in America." Mrs. Clinton forwarded the memo to Mr. Sullivan, saying "More info." (Pages 193-195)
The next day, Mr. Blumenthal sent Mrs. Clinton a more thorough account of what had occurred. Citing "sensitive sources" in Libya, the memo provided extensive detail about the episode, saying that the siege had been set off by members of Ansar al-Shariah, the Libyan terrorist group. Those militants had ties to Al Qaeda, had planned the attacks for a month and had used a nearby protest as cover for the siege, the memo said. "We should get this around asap" Mrs. Clinton said in an email to Mr. Sullivan. "Will do," he responded. That information contradicted the Obama administration's narrative at the time about what had spawned the attacks.'
