The whole premise is ridiculous. Running for president doesn’t give someone immunity from investigation. Nobody knows that better than Donald Trump, after 0bama sicced the FBI and CIA on him while he was running for president. So there’s no reason in the world why Trump should not have asked the Ukraine, where the Bidens’ corruption took place, to investigate it.
As for his temporarily withholding the aid, the hypocrisy of the Democrats edited on this forum is astounding. This aid was so important, so vital, that 0bama and the Democrats refused to give it at all. Trump was the one who decided to give this aid in the first place, so he was surely entitled to delay it if he was concerned about anything going on there.
CTLawyer, you should take your whole family and go live in some hell-hole. Trump has done a lot more for this country than you have.
