Paul Manafort leaves the U.S. District Court for the District of Columbia after a status conference on November 2, 2017.

Government lawyers told a federal judge Monday that Paul Manafort violated a gag order she issued last month.

In a filing Monday, lawyers for the special counsel's office wrote that the New Britain native and former Trump campaign manager has, as late as Nov. 30, been ghostwriting an op-ed with an unnamed Russian colleague “regarding his political work for Ukraine.” The colleague, the lawyers said, is “assessed to have ties to a Russian intelligence service.”

U.S. District Judge Amy Berman Jackson of the District of Columbia issued an order Nov. 8 barring the parties and counsel in the case from making public statements that could affect Manafort's trial.
