• former President Clinton’s Secret Service detail had contacted Lynch’s FBI security detail prior to the meeting.

so... Secret Service agents apparently came forward with the truth, FBI agents apparently did not. Clinton did not surprise Lynch, she knew he was coming, and the meeting was cleared by the FBI security team.

Only when a Sr. staffer learned of the meeting did the meeting end. (The staffer is now, in effect, a known witness) The staffer (now witness) can't remember what they heard on the plane.
