White House Visitor Logs showing John Brennan , Rachel Chandler AND Bary Obama at the WH on the same day!

All were there at the White House on 3/17/11 per White House Visitor Logs. WH Visitor logs are sloppy, as I doubt Rachel Chandler was at the WH until 3/24/11 app end date unless there was more tweek than tweens at Barry's WH. But Brennan had an appt with Barry. Rachel was there earlier in the day with a "group tour". Based on Barry's love of drugs and Brennan's love of kids, do you think they all sneaked in a meeting together?
