Trump has said many times that you do not need to send him donations but instead people are mailing envelopes to him with cash and checks and they were sending to any and all addresses. He probably has had to finally put a donation button on his website.
The facts are:
1. Trump has repeatedly said publicly that he does not need donations.
2. It would be too much trouble to send it back
3. So what if he does keep the money?
4. A few million dollars is a miniscule fraction of the
money Trump will have to spend to get into the WH.
Grasp at some other straw. This is a non starter.
The donation button has been on his website since he announced his candidacy.
Again, there's nothing wrong with him accepting donations. Every candidate does so. But don't pretend that he's not soliciting them. And don't pretend that he's fully self-funded. According to his FEC filings, he has received roughly 6 million dollars in donations so far, and has spent about 12 million dollars. In other words, contributions have funded about half of his campaign expenditures.
Once again, I'll leave it to you to decide whether you think it's misleading for him to represent that he's self-funded when half of his expenditures are funded by outside contributions.
