Everyone is quoting their favorite L-wing or R-wing source about the Biden stories. I'd like to see one final consensus report, based on sworn testimony and documented, factual claims.  I don't think that would move quickly enough through gov procedures.  Maybe someone has an extra-governmental way to do that: a multi-center academic report? a multi-media (NYT, Fox, WaPo, ...) consensus report? WARNING: such a report would likely be 100+ pages so you might have to do some actual reading.

Trump thrived at the helm of his privately held and managed companies and his zero-consequence game show.  Trump has never known Board oversight or had anyone to challenge or question his decisions (as represented by the legal scandals, above).  
.
He is hardly "thriving" as POTUS where his dictatorial approach to leadership (agree with me or you're fired), negotiation (my way or the highway), uninformed policy decisions (let's try this, no that; withdraw, invade; bomb, don't bomb; tariffs, no tariffs, Xmas, tariffs; ...), and egomaniacal narcissism is poisonous the country and beyond.

As many pointed out BEFORE the election, including Graham ("You know how you make America great again? Tell Donald Trump to go to hell.” Graham attacked Trump’s proposal to ban Muslims from coming to the United States in particular. “He’s a race-baiting, xenophobic, religious bigot” and “the ISIL man of the year” for stirring hatred against Muslims," "I think he’s going to lose and he’s going to lose badly,” he said. “You can’t nominate a nut job.” He also called Trump “just generally a loser as a person and a candidate.”" - http://www.motherjones.com/politics/2016/05/lindsey-graham-forgotten-how-much-he-hates-donald-trump/ ) , Trump was a dangerous choice for POTUS.
