In stating that Donald Trump has been bankrupt more than once, and that creditors have lost out, I am simply stating widely available facts. That is not judgment. My tax returns are available through Companies House but are remarkably boring. I did not stand for election to the most powerful position in the world, so was not invited to share them with the citizens of the United States, a recent tradition for others in that position. It is not compulsory, but it seems disingenuous for Trump to accuse rivals and predecessors of corruption while hiding his own affairs, particularly in the land of free speech taken to extremes.
If you wish to take your news from Breitbart, that is your choice and I did not criticise it. I simply pointed out that there are fact checking sources who are able to put their stories into perspective. The Washington Post offers regular updates on Trump's misinformation campaign, the New York Times has reported on his 'lies' (their word), and the partisanship of Fox News is beyond dispute. I would not recommend a single source for "completely reliable and unbiased information" but would suggest using a number of sources, ideally with conflicting views, and weighing up the supporting evidence each provides.
