Special counsel Robert Mueller on Tuesday requested that sentencing for former Trump national security adviser Michael Flynn be delayed by at least two months.

Mueller's team and attorneys for Flynn submitted that Flynn is not ready for sentencing "due to the status of the special counsel's investigation," according to a court filing in the U.S. District Court in Washington, D.C.

Flynn pleaded guilty in December to lying to the FBI as part of Mueller's probe into Russian meddling in the 2016 election. As part of the plea deal, Flynn agreed to cooperate with Mueller's ongoing investigation.

The parties are required to provide an update on Flynn's status by June 29, according to the court filing.

The New York Times reported on Monday that it had obtained a list of questions the special counsel planned to ask President Trump in a potential interview.

A handful of the nearly 50 questions focused on Flynn's firing. The special counsel reportedly sought to ask how Trump decided to fire Flynn and if the president reached out about a possible pardon at any point.

Trump's explanation for why he fired Flynn has appeared to change at times, stoking speculation that the president may have obstructed justice.

He initially said he fired Flynn for lying to Vice President Pence about contacts with Russian officials, but later tweeted that he'd fired the national security adviser for also lying to the FBI. The Washington Post reported that Trump's attorney at the time, John Dowd, authored that tweet.
