A Very Stable Genius: Donald J. Trump's Testing of America by Philip Rucker and Carol Leonnig:
Trump did achieve a victory of another sort that day. Finally, he got rid of Sessions. As election results were still being tallied the night of November 6, Trump told advisers he was eager to ax the attorney general right away. The next day, Sessions was gone.
Everything had seemed so normal the night before. Sessions; his wife, Mary; Rosenstein; and aides Isgur Flores and Stephen Boyd were hanging out in Boyd’s Justice Department office watching the election returns on Fox. Sessions knew he was not long for Trump World. Internalizing his own fragility, the attorney general had taken to quoting from Princess Bride to staffers as he left the office at night: “Good night, Westley. Good work. Sleep well. I’ll most likely kill you in the morning.”
