(CNN) Mike Pompeo has been practically everywhere following the killing of Iranian commander Qasem Soleimani.

On the Sunday after the strike, the secretary of state appeared on all five of the major Sunday talk shows to make the administration's case.

(Sidebar: Appearing on all of the Sunday shows does have a name. Because, Washington. It's called a "full Ginsburg." Why? Because William Ginsburg, Monica Lewinsky's attorney, first accomplished the five-Sunday-shows thing in 1998.)

How did Pompeo become the face of the biggest foreign policy move of President Donald Trump's time in the White House? The same way he has turned himself into the one indispensable figure in the President's circle of advisers: with unflinching and unquestioned loyalty to Trump.

Pompeo's ascent to Trump's right-hand man would have been very hard to imagine just a few years ago.
