I think those who are pushing the “Trump is a cheap SOB” meme are doing no favors to their preferred candidate.
All you have to do is a simple google and if you are honest you see they are involved and have been involved for a long time in their favorite causes. Those who criticize Trump for lack of charitable work are really not honest and filled with hate for the guy. The Trump organization has donated and raised hundred of millions. It is there for all to see.
