Yep.
“The Trump presidency that we fought for, and won, is over,” Bannon said Friday, shortly after confirming his departure. “We still have a huge movement, and we will make something of this Trump presidency. But that presidency is over. It’ll be something else. And there’ll be all kinds of fights, and there’ll be good days and bad days, but that presidency is over.”
If you read the actual article, and parse what Bannon said, he’s clearly indicating that the first phase of Trump’s presidency is over...they’re moving into the next phase, and Bannon’s departure is part of it. This twit thread from Thomas Wictor explains it nicely:
