The governor praised Burris' integrity and said he hopes that the allegations against him don't "taint this good and honest man."
Burris says he's eager to get to work in Washington. He says he's proud of his accomplishments and vowed to uphold the integrity of the office.
Burris says he has no connection to the charges against Blagojevich, who was arrested on Dec. 9 and accused of trying to profit from appointing Obama's replacement.
Burris was the first African-American elected to major statewide office. He's served as Illinois' comptroller and ran for governor three times -- the last time losing to Blagojevich.
