you'll remember the last president to embark on a trip this arduous. president george bush h.w. bush in 1992, a trip that gave us this memorable moment. the president getting sick on the japanese prime minister's lap. i want to ask all three of you, start with alexander before we go. do you think in all seriousness, the president has the stamina to pull this trip off? >> they must think he does, given how they're scheduled it. and he went to hawaii today, obviously to acclimate to the time change. i think it might be good for him to -- hopefully it will wean him off twitter. >> we'll see about that. john, let me ask you. he couldn't stay off twitter on several of his other international trips. is he going to do it now? >> elder bush had a vaseo vagual incident that ended up on tv. >> i can relate. i've had one myself.
