I don't remember all the details but this is what I could find

This was the building that was raided that his investment firm had ties to: https://abc7chicago.com/post/ex-residents-south-shore-chicago-apartment-building-targeted-massive-immigration-raid-seek-millions-damages/19107787/

I did find that some building shares were sold after an unrelated scandal, but I think it was this firm that had ties to the building in Chicago that was blitzed. https://www.rawstory.com/2018/10/jared-kushners-family-selling-chicago-building-center-pay-play-scandal/

I wish I had thae article Im thinking of on hand, but i read it shortly after the raid occurred, so it was about a year ago. I remember reading how this blitz style raid traced back to shady dealings and an investment in real estate by kushner.
