If Trump is receiving money from these parties this, it is irrelevant. It's not a conflict of interest because there has been no proof that this has affected Trump's decisions in the workplace, or that there has been a clash of personal and professional interests. There are just accusations that their could be a clash.
If Trump is using his status as POTUS to further his personal financial interests, then that is absolutely a conflict of interest because he is supposed to be putting the interests of America before his own.
Again, if you or anyone wants to give me money I would just say thanks and be on my way about it. It's not a given that I am going to owe or give you anything back.
Trump is in a position to return favors, you are not. That’s why he’s getting lavish gifts from shady governments and big corporations while you get screwed by footing the bill to upgrade then decommission an Air Force One that probably will never be used as Air Force One. Pray tell, why decommission it when it would make far more sense for it to serve future presidents? Trump is trying to cut wasteful spending, isn’t he? Maybe DOGE should take a look at this deal.
