"Nothing about it", he said in response to a reporter's question.
Manafort also did not initially disclose having earlier discussed a Ukraine peace plan with Kilimnik on more than one occasion during the campaign, according to the filing.
Manafort's lawyers maintain that all of their client's misstatements to Mueller "were not intentional" and happened because he was poorly prepared for his meetings with the special counsel, which started days before he pleaded guilty and then began in earnest the day after his September 14 plea hearing.
That information was included in a court filing this week that appeared to inadvertently include details not meant to be made public and indicates a pathway by which the Russians could have had access to Trump campaign data. He also has a March 5 sentencing before Jackson in Washington for his guilty plea on conspiracy against the USA and conspiracy to obstruct justice.

Another witness, testifying against Manafort under oath, said Manafort and Akhmetov "knew each other well".
Former Trump campaign manager Paul Manafort departs from U.S. District Court in Washington, U.S., February 28, 2018. The U.S. and European Union have imposed sanctions on Russian Federation over that move as well as the country's support for separatist rebels in eastern Ukraine.
The sharing of the polling data with Kilimnik was revealed this week, despite being redacted in a court filing, due to a formatting error. President Trump denies any campaign collusion with Russian Federation.
"Issues and communications related to Ukrainian political events simply were not at the time forefront of Mr. Manafort's mind during the period at issue and it is not surprising at all that Manafort was unable to recall specific details prior to having his recollection refreshed", they said.
But that plea deal fell apart after prosecutors accused him of lying. The request to use Manafort as an introduction to Trump came while Manafort was under indictment in two federal cases.
Special counsel Robert Mueller's team has been circling Lyovochkin and Akhmetov's dealings with Manafort for a while, as they were both key, generous backers of Manafort's Ukrainian lobbying work, prosecutors said at Manafort's financial fraud trial last summer.
