As to what Trump thinks Biden and his son Hunter did wrong:
Trump's claims that Biden pushed for the firing of a Ukrainian prosecutor because he investigated a business for which his son served as a board member have previously been found to be false. The prosecutor was seen as corrupt by multiple governments and international institutions, not just the former vice president.
The former Ukranian Attorney General said:
The then-Ukrainian prosecutor general Yury Lutsenko said in May that Burisma Holdings, a major energy company, did not violate Ukrainian law by having Hunter Biden on its board and paying him.
Trump, with his customary inarticulate manner of speaking said yesterday:
Trump on Sunday...said that he did indeed discuss Biden with Ukraine's president at a time when Kiev was awaiting a $250 million military aid package from the United States. The call with Zelensky took place on July 25. Congress passed the bill in August and the White House lifted a hold on the money in September.
"The conversation I had was largely congratulatory, with all of the corruption taking place and largely the fact that we don't want our people like Vice President Biden and his son creating to the corruption already in the Ukraine," Trump said.
I assume he meant "contributing". Is he losing his marbles or does he just not have very many to begin with....or both? I think America deserves a leader who can properly express his thoughts in the English language.
I don't think Senate Republicans will vote to impeach Trump over misconduct pertaining to Joe Biden, especially in an election year. But it is another reason not to nominate Biden. Trump will turn the election into a referendum on whether Biden and his son engaged in misconduct rather than the important issues facing the country. The post-primary campaign would be a replay of Trump's distortion of the Hillary email story that will resonate with his underinformed supporters who will just love a rally where they can shout "lock him up".
