I'm going to give an unpopular opinion. I am no fan of Trump but a supposed news like site Buzzfeed shouldn't be posting news by saying we have no idea if this is true or not, we'll let you decide. Yes, the details are salacious and everyone is getting a good laugh but if "fake news" is a problem (and I think it is to a degree) then this shouldn't be the standard of publishing. Moreover, this guy Cohen who was supposed to be in Prague, was never there. He was at USC with his son (this has been confirmed). I know that Trump is the devil and if he says the sky is blue it needs to be rebutted but let's be fair about what we are doing here.
Just because he has gone and said things with no proof, that does not grant us permission to do so as well. Additionally publishing this stuff allows the ignoring of bigger issues with Trump as president.
