The famous "Newsweek meeting." Let me explain. In January 1967, RFK was on a European tour of the UK, France, Germany and Italy. In Britain he met Wilson at No 10, he also met de Gaulle and senior French Quai d'Orsay officials. The last of those meetings involved a meeting with the QdO's Far East expert, Etienne Manach. They discussed the possibilities for a negotiated 'Nam settlement. No one is really certain what happened there- quite possibly there was a translation (RFK being unilingual) error. in any case, it was leaked to Newsweek by an unknown bureaucratic source that something concrete had been proposed, which was promptly published. So LBJ finds out, he's furious- in his now fully-established anti-RFK paranoia, he thinks RFK did it, which he did not. When he returns, a prompt White House summons...
The conversation went like this, despite non-denial denials to the contrary on both sides.
LBJ: "You were the source for that article."
RFK: "No, Mr. President, I was not. While on my tour, I found that in..."
... (civil discussion)
RFK: "They all agreed that the best chance of peace was a bombing halt as a prelude to negotiations."
LBJ: "There isn't a chance in hell I would do that. I will destroy you and each and every one of your dove friends- you have blood on your hands."
RFK: (pounds fist on desk, gets up abruptly): "I don't have to take that shit from you!"
LBJ cuts him off at the door: "Tell them that you received no peace feeler- Vietnam was not discussed."
RFK: (sullenly nods, leaves)
LBJ to Katzenbach (the witness): "Spin this as best you can."
