The whole thing was a years-long entrapment scheme.
The effort was 100% trolling and 100% bait to get Trump entrapped into doing anything that could be obstruction. He did say things (according to the report that could be interpreted as attempted obstruction but these things were not carried out so there was no obstruction). They knew this whole thing was so outrageous that 99% of people would entrap themselves with an emotional reaction. Trump did not. Fail.
And my guess is that doing business in NYC has exposed Trump to a few entrapment schemes.
