This is a real possibility. But the question is: why now? Adams is a Democrat mayor in a deep-blue Democrat stronghold, who will face the same obvious lawfare as Trump faced - creating a stir just weeks before a national election.
As a political strategy, I don't see how this benefits Harris, Biden, or the Democrats "messaging" in any way.
The messaging from Democrats is that New York is already owned by one faction and that the Turks or anyone else needs to butt out.
It's no different that an anonymous tip to police to put your drug-dealing competition out of business.
To the dealers - "You'll get locked up."
To the backers - "We'll get your boy locked up and your assets seized. The Feds, the NYPD, and the prosecutors work for us, not you."
