Attorneys for Rod Blagojevich have formally begun the process of appealing the former governor's conviction and prison sentence.
They did so in a court filing late Tuesday, notifying the U.S. District Court in Chicago that they intended to appeal to a higher court.
Blagojevich has been ordered to report to prison on March 15. The 55-year-old was convicted earlier this year of corruption charges that included allegations that he tried to sell or trade an appointment to President Barack Obama's vacated Senate seat for campaign cash or a top job.
Attorneys had said they planned to appeal.
However, the process of filing a full appeal is likely to drag on for several weeks or even months. After notification, transcripts and other documents are typically transferred to the higher court.
