President Donald Trump plans to cancel security clearances and government work for Covington & Burling because the law firm has aided special counsel Jack Smith.

The memorandum signed by Trump yanks the clearances of “Koski and all members, partners, and employees of Covington & Burling LLP who assisted former Special Counsel Jack Smith during his time as Special Counsel, pending a review and determination of their roles and responsibilities.”

Covington, a prominent D.C. law firm, is the latest target of the President’s campaign of retribution over the criminal investigations that dogged him before he returned to office.
