Roger Stone, a longtime ally and confidant to President Donald Trump, pleaded not guilty in Washington federal court Tuesday, accompanied by his out-of-state attorneys after an initial hiccup in court filings raised uncertainty about his representation.

The Republican operative appeared with Fort Lauderdale, Florida-based attorneys Robert Buschel of Buschel & Gibbons and Grant Smith of StrategySmith after a magistrate judge twice said Monday that they failed to follow local rules to appear. Stone was also joined by D.C.-based lawyer L. Peter Farkas of Halloran Farkas + Kittila.

Magistrate Judge Deborah Robinson first issued an order Monday morning stating that Buschel and Smith had failed to file motions to appear pro hac vice signed by a sponsoring member of the D.C. Bar. In a subsequent order denying the pro hac vice motion filed later Monday, Robinson noted that Farkas, whose name appeared on the signature lines of the motions, did not file the motions and had not filed a notice of appearance.
