The Chicago Sun-Times says that U.S. Sen. Roland Burris must resign.
The Sun-Times called for Burris to step down in a newspaper editorial published Thursday, saying Burris "has lost the last shred of credibility." The newspaper also says U.S. Sen. Dick Durbin needs to ask Burris to quit.
The Chicago Tribune, The Washington Post, The State Journal-Register in Springfield and the Peoria Journal Star also have called for Burris to resign. The Rockford Register Star said in an editorial that Burris should retire when his term ends in two years.
Former Gov. Rod Blagojevich appointed Burris on Dec. 30. Since then, Burris has offered several explanations of events surrounding his appointment, including being solicited for fundraising assistance by Blagojevich's brother.
