(CNN) George Papadopoulos' apparent double speak about his guilty plea may hurt the former Trump campaign adviser's chance of delaying his prison time, following a series of court filings in the past week.

Papadopoulos was sentenced this fall to 14 days in prison for lying to investigators about his contact with Russian affiliates during the campaign, a charge he admitted in court and for which he expressed remorse when speaking to a judge. But outside of his criminal court proceeding, Papadopoulos has publicly railed against the FBI, the Russia investigation and his plea deal.

Papadopoulos is set to report to the federal Bureau of Prisons on Monday to begin his jail time. He has asked the judge to delay the start of his sentence. He claims his sentence should be paused while a court of appeals considers the constitutionality of Robert Mueller's appointment in a separate case. The judge overseeing his case, Randolph Moss of the US District Court in DC, has not yet made a decision on Papadopoulos' requests.

But Mueller's Office of Special Counsel, which charged Papadopoulos with the crime last year, asked on Wednesday for the judge to keep the current schedule for Papadopoulos to serve his time.

The prosecutors accuse him of using his recent requests to the court merely "for the purposes of delay."
