From a few days back, but I'm surprised this didn't hit harder on the news. Perkins Coie was the law firm contracted to do oppo research on Trump during his 2016 campaign, which sourced the infamous Steele Dossier from FusionGPS. The EO strips the firm of all its contracts, directs EEOC to investigate their (past!) DEI initiatives and hiring, forces all contractors to inform the government if they do any business with Perkins Coie (even as part of other contracts), blacklists every employee from ever being hired by the government, strips them of their security clearances, prohibits Federal employees from interacting with anyone from Perkins on official business, and even bans employees from setting foot in any Federal building! It also threatens other large law firms.

Trump's administration has done plenty of heinous things so far, but this blatant exacting of revenge against entities external to the executive branch feels like a new low.
