WASHINGTON — A federal judge ruled on Wednesday that Paul Manafort, President Trump’s former campaign chairman, repeatedly lied to prosecutors after he agreed to cooperate with the special counsel’s investigation into Russia’s interference in the 2016 election.
The decision by Judge Amy Berman Jackson of United States District Court may affect the sentence she hands out in the coming weeks to Mr. Manafort, 69. Judge Jackson said that Mr. Manafort had intentionally lied about his contacts with a Russian associate during the campaign and after Mr. Trump was elected.
Prosecutors have said that the associate, Konstantin V. Kilimnik, has ties to Russian intelligence services. The judge also found that Mr. Manafort had lied about a payment that was routed through a pro-Trump political action committee to cover his legal bills, and about information relevant to another undisclosed investigation underway at the Justice Department.
Mr. Manafort was convicted last year of eight felonies, including tax and bank fraud. He later pleaded guilty to two additional conspiracy counts in a case before Judge Jackson, and agreed at that point to cooperate with prosecutors from the office of the special counsel, Robert S. Mueller III.
Judge Jackson ruled in Mr. Manafort’s favor on two issues. She decided that prosecutors had failed to prove their assertion that Mr. Manafort had deceived them about Mr. Kilimnik’s role in a conspiracy to obstruct justice to which Mr. Manafort pleaded guilty. And she decided that the prosecutors failed to establish that Mr. Manafort had lied about later contacts with Trump administration officials.
