Marie Harf says of course they were wiretapping Flynn, he was speaking to Russians about undoing Obama policy and that was outrageous! Certainly not a crime. The incoming President's security advisor has every right to discuss the new President's foreign policy objectives with any country. They could hark back to the Logan Act, but that has never been enforced.
Obama was talking to the Iranians before he took office.
Considering policy other than Obama's was apparently a crime in their eyes and justified them wiretapping Trump and then leaking such to the Washington Compost. Flynn's crime was lying to FBI about it and that's why he was fired by Trump.
We knew all this ... there is no there there ... Trump is POTUS!
Now as for those who were doing the wiretapping ... TBD ;)
