One of the FBI raids targeted an office Michael Cohen keeps at the New York office of Squire Patton Boggs. Cohen formed a "strategic partnership with the firm last year. motherjones.com/politics/2018/…
In the wake of the raid, Squire Patton Boggs says that partnership with Cohen "has reached its conclusion, mutually and in accordance with the terms of the agreement." 
News: Squire Patton Boggs says Cohen is no longer their partner. And: "We have been in contact with Federal authorities regarding their execution of a warrant relating to Mr. Cohen. These activities do not relate to the firm and we are in full cooperation.”
Good news for Cohen: He still has his position as one of the RNC's National Deputy Finance Chairmen. Or so the RNC's lack of comment suggests.
In fairness to Patton Boggs, I was told prior to today that they were looking at ending their partnership with Cohen. But it seems to have taken an FBI raid in their office to get them to officially, publicly end the arrangement.
