Stop obstructing the investigation and allow first hand subpoenaed witnesses to testify, is the only way to settle it.When they have no evidence, and hearsay is all they have, what do you expect the demoncrats to say.
Funny how the Rs are screaming about this when THEY are the ones preventing it....
Let's have Mulveney, Giuliani, the 2 Russian Ukrainian American thug partners, Bolton, his assistant, etc and the President testify, they were first hand.....
Do you think Giuliani went rogue, or Sondland went rogue and the President was unaware??
