“Again, I-I-I don’t know exactly what — we really thought — and again I don’t want speak for any senator,” Johnson responded. “I really thought he was going to vote yes to send that to conference at 10:30 at night. By about 1, 1:30, he voted no. So you have talk to John in terms what was on his mind.”
