Yep. It appears that's how this is going to play out.
The President has been patient with Sessions, but he's now out of time. The enemy has gained a real foothold and must be stopped before gravity overtakes the situation. He's got to put an AG in place who will mount a real offense while there still time to win the battle.
It sure looks like it. Firings or resignations are coming in August and to fill the vacancies with immediate appointments.
