I can't tell because this ABC article doesn't name the law firm representing Trump.
Law Firm Stops Representing Trump Campaign in Pennsylvania Suit
Porter Wright Morris & Arthur, the law firm leading the Trump campaigns efforts to cast doubt on the presidential election results in Pennsylvania, abruptly withdrew from a federal lawsuit that it filed days earlier on behalf of President Trump.
Plaintiffs and Porter Wright have reached a mutual agreement that plaintiffs will be best served if Porter Wright withdraws, the law firm said in a federal court filing.
The firms withdrawal followed an article in The New York Times on Monday described internal tensions at the firm about its work for Mr. Trumps campaign in Pennsylvania. Some employees said they were concerned that the firm was being used to undercut the integrity of the electoral process. One Porter Wright lawyer resigned in protest over the summer.

I hope it's the same suit, but I don't know?
