of an american president, pay respect to the war dead, 100th anniversary of the first world war. the president says i'm not going to go, because i'm not going to motorcade. his chiefs of staff and general joint chief say get us a motorcade. >> there are a couple of things we should note. yes, the president probably couldn't have taken the helicopter because of weather reasons. that's happened with other presidents. that's not unique. as other officials have noted yesterday there's always a backup plan for a president. i've been on numerous presidential trips and there's almost a way for the president to get where they need to go. it might ruin the schedule or take a longer time but there's a way to go. i can't imagine anybody other than the president of the united states made that call ultimately
