Still, you prefer to argue semantics. All you're doing is concentrating on anything and everything other than Trump, withholding money from a foreign nation till they dig up dirt on a political opponent. That's the only issue in the impeachment hearings.
1. If you want to investigate Biden, go for it. That's a separate issue.
2. If you want to investigate the Russian infiltration of the NRA and their non-profit status, go for it, but it's a separate issue.
3. If you want to investigate area 51, go for it but it's a separate issue.
You can talk all day about anything and everything other than the only fact that needs to be discovered regarding impeachment. It does nothing to change the facts regarding impeachment.
