Osama bin Laden endorsed Biden? Is she low key suggesting he's not really dead and the "burial at sea" was a hoax? Alert Alex Jones at once!
I assume that’s a reference to what Bin Laden wrote about his support for a plot to kill Obama and Petraeus back in the day:

As for Petraeus, he is the man of the hour … and killing him would alter the war’s path.”
