There's a conspiracy theory which says Trump supporters in the government are being fired or forced to resign one by one. Flynn and Bannon are gone. H.R. McMaster is said to be firing other pro Trumpers working for the state. That could be part of a plan to isolate and weaken Trump before removing him from power.
Many in the media and politics are calling for Trump to be impeached.
There is a chance it could happen.
I think the chance is quite real. He's doing so many stupid things and with his own administration crumbling, that's not gonna become better for him.
