There are now TWO state department witnesses to that call.
Sondland will have to say whoopsydaisy and update his testimony. He is also now a direct witness of Trump's own involvement in the shakedown. He talked with him about it. He said Trump didn't give a damn about Ukraine, only Biden, right after the call!!! So much for caring about corruption in Ukraine.
Trump is boxed in with a bow on it. There's really no way out because it is clear that there was extortion and bribery involved. It was exactly what impeachment is for.
The real issue is whether there are enough honest senators to do a proper trial.
