Sun-Times Media CEO Edwin Eisendrath said in a statement released Saturday that Konkol came to the Reader "bringing great hope for a new direction and a new life to a storied brand."
"A tumultuous ten days culminated in the publication of a Reader cover that we believe was not in line with either our vision for the Reader or that storied history," Eisendrath wrote.
On Thursday, the Reader's cover featured a racially provocative cartoon of J.B. Pritzker that referenced the candidate's controversial comments about black political leaders.
The cartoon shows Pritzker sitting on a lawn jockey and making a phone call that is being wire-tapped.
Some readers called the cartoon race-baiting.
