Robert Caro says John Connally collected and distributed money at Lyndon Johnson's direction and could explain how Johnson used money to gain political power and selected recipients.

“You ask, you ask terrific questions. Sometimes you're sitting there and you know this person doesn't wanna talk to you about what you wanna get out from, like John Connally on how Johnson used money to get political power.”

“And, and I'm thinking, "But I've been through the notes. Connally collected the money and gave it out at Johnson's instructions, so he's the only guy who can tell me how Johnson did this, you know, how he judged who to give money to."”
