President Donald Trump was left more beleaguered and isolated than ever after the resignation of his confidante Hope Hicks, one in the core of "originals" who had nurtured the iconoclastic tycoon all the way to the White House.
Hicks dropped her shocking announcement on a day that was bewildering even by the extreme standards of this White House, leaving Trump's presidency looking increasingly unmoored.
The departure of Hicks -- the young woman who became as much an emotional crutch as a communications director -- leaves the inner circle of a President for whom loyalty is an obsession in tatters.
"As a CEO, or as a President or anyone at the top, it is lonely, and when you go in there you have the team, and you have your team," Rob Astorino, a longtime friend of the President's, told CNN's Erin Burnett on Wednesday. "Your team are the people that know you best and you really, really trust."
"
Hope was one of the people he really, really trusted," Astorino said. "
So with her leaving, there is only a handful left, and he's going to feel like he is on an island."
Hicks' departure will come at a moment of maximum instability for the White House, with staff morale plummeting and the prowling presence of special counsel Robert Mueller and his Russia probe becoming ever more oppressive.
Trump's White House has been a whizzing revolving door for aides, officials and cabinet members whose stars often burn bright, then quickly burn out. Outsize personalities like Steve Bannon, fixers like first chief of staff Reince Priebus and retainers like Sean Spicer are all long gone.
But Hicks is one of the first among equals whose loyalty to Trump is unquestioned, and her exit will particularly sting, several aides told CNN. Not many people are irreplaceable. But for Trump, Hicks probably is.
"I don't think it's possible to overstate the significance and just the importance of her role within the White House. She's an invaluable team member and one of the originals," one Trump ally told CNN's Jeremy Diamond.
The loss of Hicks comes with other pillars of the President's Oval Office support network already felled or wobbling badly.
The political careers of Jared Kushner and Ivanka Trump are teetering, with the President's son-in-law's lost top-secret security clearance threatening his role as Trump's foreign policy consigliere.
Earlier soul mates like former campaign chief Corey Lewandowski never made it to the White House. Keith Schiller, Trump's former bodyguard, left last year.
National security adviser Mike Flynn was gone in disgrace after a couple of weeks. And Trump's billionaire pal Tom Barrack didn't sign up for political service, nor did the President's ultra-loyal gatekeeper of many years Rhona Graff.
One loyalist who is still around is social media specialist Dan Scavino.
All of Trump's departed inner circle friends will still be available to him on the outside, for the President's daily roster of calls to vent and solicit advice.
But it's looking possible that soon, none will be by his side, and that means life in the Oval Office could get very lonely indeed for the President.
