The current occupant of the White House is far from hesitant about demanding loyalty from those who serve in the White House, his cabinet or Congressional Republicans. If you don't believe me, you can just check with former FBI Director Jim Comey or read his new book, “A Higher Loyalty,” or ask those, like Reince Priebus, who sat around the table in the White House and took turns sharing how honored they were to serve the president.
If you need another example of the rampant sycophancy crucial to dealing with this president, you can also check with the swarm of Congressmen who took turns coming to the microphone on the South Lawn of the White House praising the president in the aftermath of passing that horrendous tax bill.
Senator Orrin Hatch even went as far as stating Trump may be the greatest president ever. Really, now!
