There's a giant bus that Sondland just threw literally everyone under.
Sondland donated a huge amount of money to Trump and that's how he got his seat.
Loyalty cannot ever go in just one direction, when it does, when the shit hits the fan, everyone will start eating one another while rats flee the ship.
By the end of this the Senate very well may vote to remove him from office, then use their remaining majority in the senate under Pence to stack the courts as heavily as possible before Pence and McConnell lose their elections next year.
I do not think McConnell survives in Kentucky next year. He's gone from "He's a piece of shit but he's our piece of shit" to "Someone put this turtle on its back on the highway in front of a fast moving semi please"
