At 6:30 am, John Kennedy asked Robert Kennedy to prepare an estimate of upcoming electoral votes "including Texas".[79] Robert called Pierre Salinger and Kenneth O'Donnell to assist him. Salinger realized the ramifications of counting Texas votes as their own and asked him whether he was considering a Kennedy–Johnson ticket, and Robert replied "yes".[79] Caro contends that it was then that John Kennedy called Johnson to arrange a meeting; he also called Pennsylvania governor David L. Lawrence, a Johnson backer, to request that he nominate Johnson for vice president if Johnson were to accept the role. According to Caro, Kennedy and Johnson met and Johnson said that Kennedy would have trouble with Kennedy supporters who were anti-Johnson. Kennedy returned to his suite to announce the Kennedy–Johnson ticket to his closest supporters, including northern political bosses. O'Donnell was angry at what he considered a betrayal by Kennedy, who had previously cast Johnson as anti-labor and anti-liberal.
