A Higher Loyalty: A new book lashing out Trump by James Comey

In the memoir, the former FBI director calls the US president ‘unethical, and untethered to truth’.

Unethical, ego-driven and with a leadership style like that of a mob boss.

That’s the scathing assessment of US President Donald Trump in a new book by the former FBI Director James Comey.

It comes less than a year after Comey was fired by the president.

The book titled, A Higher Loyalty: Truth, Lies and Leadership, comes out next Tuesday at a time when the president is already besieged with domestic problems.
