WASHINGTON — President Trump’s former campaign chairman, Paul Manafort, and an associate with ties to Russian intelligence drafted an op-ed article last week about Mr. Manafort’s work for Russia-aligned interests in Ukraine, according to a court document filed Monday by the special counsel, Robert S. Mueller III.
The filing seeks tougher bail restrictions against Mr. Manafort, arguing that writing the op-ed flouts a judge’s admonition against trying to use the news media to influence the case against Mr. Manafort and Rick Gates, another former campaign official.
Mr. Manafort and Mr. Gates have pleaded not guilty to charges of money laundering and lobbying violations that were related to their work for Viktor F. Yanukovych, the former Ukrainian president.
Monday’s motion does not name the associate with whom Mr. Manafort is believed to have worked on the op-ed. It identified the person only as “a longtime Russian colleague of Manafort’s, who is currently based in Russia and assessed to have ties to a Russian intelligence service.”
A person close to Mr. Manafort identified the associate as Konstantin V. Kilimnik, who worked for years as Mr. Manafort’s right-hand man in Ukraine and continued communicating with him throughout the 2016 presidential campaign.
Mr. Kilimnik was born in Ukraine when it was still a part of the Soviet Union, and he served briefly in the Russian Army as a linguist, later telling associates that he had a background with Russian intelligence. But this year, as scrutiny mounted of his work with Mr. Manafort in Ukraine, Mr. Kilimnik steadfastly denied any association with Russian intelligence. And an investigation by Ukrainian prosecutors into Mr. Kilimnik’s possible links to Russian spy agencies was closed late last year without charges.
