Do you think LBJ was in on it? We’ve certainly all seen the famous foto of LBJ winking at someone during his hastily-arranged swearing-in.
In on it? He orchestrated it.....................
Jackie did.
There was a route change that occurred, and LBJ got intensely involved to change it back to the original plan.

Read the book The Texas Connection. It lays out the facts!
