Why can't they drag it out and subpoena Ciaramella and Hunter Biden? Oh, thats right. Such proceedings would also inadvertently implicate Lindsey Graham.

The other possibility is that they know the nation is sick of hearing about impeachment and they know it, so they want to quash it since it's in their court. When you have a president that has a higher "not support impeachment" rating than approval, this charade has become like a dirty diaper that no sane politician would want to be near.
