President Donald Trump’s letter firing then-FBI Director James Comey was initially sent to the wrong printer, according to a new book excerpted in Axios Wednesday morning.

[National Economic Council Director Gary] Cohn told his aide to take the letter straight to [then-White House counsel] Donald McGahn, who also had an office on the second floor of the White House (and whose printer it had clearly been meant for). Upon receiving it and realizing it had been printed in the wrong place, McGahn said, “Oh, f!@#!”
