“It is still unclear why it took the whistleblower 18 days to report such an allegedly egregious abuse of presidential power.”
I’m sure it was a difficult decision for the whistleblower. He/she/it probably struggled for days on end trying to reach an appropriate choice. As a loyal American they, no doubt, found it extremely difficult to turn on a duly elected President. Finally, after many long soul-searching nights and much prayer, they choose to support freedom, truth, apple pie and the American way.
