Per White House Logs
Bilal Askaryar White House Visits, four times.
There are four items listed, but one is March 20, 2015 at 9:00 a.m. and another is March 20, 2015 at 10:30 a.m. Do you really believe those are two separate incidents? I rather doubt Askaryar left the White House between those two events.
I think it is important that we neither understate this case (the SecEd wasn't assaulted) or overstate this case (four visits when two line items were essentially the same visit).
