Here's Trump making clear that he does not intend to back Bolsonaro's now-deleted claim that he is the "true president-elect of Brazil." When I called around in the US Govt to try to understand why that statement was issued, nobody understood it:
It seems as Flavio Bolsonaro and his allies just deleted that statement in which Flavio declared himself "the true president-elect of Brazil," and then re-posted the letter without that declaration.
I had just spent 30 minutes speaking to everyone I could trying to understand how it made any sense at all to make this claim -- either in general or the way they did it: so impulsively and suddenly, with no groundwork laid for it -- and nobody could make sense of it. So it seems wise that they removed it.
