The "Players" are discussing the Mueller appointment at about 2:45 p.m. the day it was made, May 17,2017.
According to the NY Slimes that same day (posted to website initially):
"Mr. Trump was notified only after Mr. Rosenstein signed the order, when the White House counsel, Donald F. McGahn II, walked into the Oval Office around 5:35 p.m. to tell him."
