Any "misstatements" made by U.S. President Donald Trump's former campaign chairman, Paul Manafort, to federal prosecutors were "unintentional" and he would not seek a hearing to contest the allegation he lied, Manafort's lawyers said in a court filing.

Manafort was responding to allegations in December by the U.S. special counsel investigating Russian meddling in the 2016 presidential election that Manafort had told "multiple discernible lies" to investigators, breaking a plea agreement struck in September.

Manafort's lawyers had been given until Monday to decide whether they would challenge the allegations, a move that would require a court hearing to weigh evidence, or simply ask the government to move on to sentencing. The filing was submitted under seal on Monday, and a redacted version released on Tuesday.
