For all intensive purposes both the Nixon administration and the Clinton administration co-operated with the investigation. Trump never considered co-operating. Both Clinton and Nixon understood the perils of impeachment for both parties and the harm it is does to the country. An impeachment always further divides the nation making bi-partisan efforts nearly impossible. It also makes the process just another method for changing presidents, not a good thing. Unfortunately, Donald Trump sees impeachment as just another personal battle with little thought for how it effects others and the future of the nation.
I believe the House investigation should culminate with a decision to do what the Senate will most likely do, leave the decision of wrong doing in the hands of the voters.
To be honest, the Dems aren't acting too concerned about how this mess affects the entire nation either.
Question: what the EFF is Trump supposed to do? The Dems have been after his ass since the day after the 2016 election, with no actual evidence to base any of their investigations and inquiries on. Has he not released the transcripts of the phone call? Should he not expect reasonable attempts by the Dems to allow him or his people to question the same witnesses and ask whatever questions they deem appropriate?
Question: does Biden get off the hook for whatever he or his son did with respect to Ukraine, because he's running for the Dem nomination? Should we the public not know about whatever took place while Biden was the VP? Why isn't that actually part of his job as President, to look into any possible illegal activities in another country to see if our own laws were broken? Shouldn't he find out?
What is Trump suppose to do? Well to start off, he could start acting like a president instead of narcissistic school boy who's only interest is himself. If he had real information that Biden's son has violate the law, then he would have his AG open an investigation instead trying to bribe a foreign government with military aid.
Of course all he really wants is President Zelensky to announce he is opening and investigation into Biden. Then he could spin all kinds of stories about Biden at his rallies. Of course he will probably do that anyway.
1) Trump never bribed anybody.
2) Never was any investigation.
3) Ukraine got the US aid.
That's because he got his fingers caught in the cookie jar. If the whistle blower didn't spill the beans, Trump would have have probably got away with it.
The President of the United States reserves the right to withhold US money to a country for any reason. Joe Biden ,speaking on behalf of DumBama, openly stated that if the prosecutor that looked into the firm his son was working for, wasn't fired by the time he left Ukraine, all bets are off. But that was okay.
Can one of you TDS people riddle me this: The accusation is that Trump "bribed" Zelensky with US money in exchange for a Biden investigation. Fine. Then please tell me why nobody in Ukraine (including Zelensky) knew there was any hold on the money until a month after the phone call. If Trump bribed Zelensky, wouldn't you think he'd be the first to realize it?
So it seems, not only do us Republicans not see any bribe or quid pro quo (which is not against the law) but neither did anybody in Ukraine.
