A federal judge on Monday canceled a sentencing hearing for former national security adviser Michael Flynn that was scheduled for later this month.

Judge Emmet G. Sullivan of the U.S. District Court in Washington issued an order putting off the Feb. 27 hearing pending a new order from him.

The move represents the latest turn in the case against Flynn, who pleaded guilty in December 2017 to lying to the FBI about his contacts with Russian Ambassador Sergey Kislyak. Federal prosecutors once suggested probation for Flynn, then shifted to include prison time, and then said in a late January court filing that probation remained a “reasonable sentence.”

The prosecutors’ Jan. 29 filing was submitted as Flynn continued his effort to withdraw his guilty plea. He was charged in connection with special counsel Robert S. Mueller III’s Russia investigation.
