When John Glenn was going into space, Johnson pulled up in front of her house, insisting on going live on air with her; she called Glenn at NASA and he told the people down there that if she had to talk to Johnson on TV, he was going to take off his flight suit and go home.
NASA made Johnson leave -- he was FURIOUS. But he was just going to use her.
She had a HORRIBLE stutter and hardly ever speaks in public.
I never heard that story and good for John Glenn for protecting his wife.
