You're reading this wrong:
>Hussein [WH [call] [tarmac] BC/LL] #RR# >Obama called the WH about the Tarmac Bill Clinton L Lynch info - RR????
Read the brackets.
White House [call] [tarmac] BC/LL within the outer bracket. So the object of the White House call is (call is to) the tarmac and BC/LL.
Who made the call? Hussein. Rosenstein knows it.
