A prosecutor did not rule out the possibility Friday that the special counsel's office would bring additional charges against Paul Manafort for allegedly violating his September plea deal.

Andrew Weissmann, a top prosecutor working under Special Counsel Robert Mueller III, said his team was prepared to detail how Manafort, the onetime Trump campaign chairman and Connecticut native, broke his plea agreement by lying to investigators. When asked by Judge Amy Berman Jackson whether the special counsel planned to charge Manafort over those allegedly false statements, Weissmann replied, “That determination has not been made yet.”

Berman Jackson set a Dec. 7 deadline for the special counsel to lay out Manafort's alleged lies. She also set Manafort's sentencing for March 5, but signaled the date could change as prosecutors and Manafort's defense lawyers duel over whether the plea agreement was breached.
