Trump actually put out another statement today telling supporters of the GOP to donate money directly to him, instead of donating to the party / committees within the party. Here is that:
Oh fantastic. It's also great to see NYT acting as his proxy on Twitter
In case of any doubt about Trump's motives, money is always a safe bet. I have long believed that he will stay in politics after losing the 2020 election just to collect donations (and launder them through his properties etc), just didn't think he'll do it so blatantly. But why not, he owns the party, he can do no wrong.
