Unfounded Rumor from the Rumor Mill: Is Trump backing AOC's Senate race in New York?

A friend of mine said he "heard" it somewhere. I don't trust what he reads or hears...and can't find any corroboration on the internet.

As I told my friend, it would be a Machiavellian move if true. Not sure if AOC's supporters would abandon her in horror, or if this move would make her MORE popular in her district among those whose minds are as twisty as mine.

Is this just total BS from the BS factory?
