Here's the Examiner's announcement and the Chronicle's take.
When it comes to covering pro teams, Mariotti was never a homer. Former Chicago White Sox manager Ozzie Guillen called him a gay slur, but apologized later. When Mariotti left the Sun-Times in 2008 to write for AOL, and proclaimed print was dead, Roger Ebert wrote a scathing column about Mariotti titled "Jay The Rat."
Mariotti lost his gig at ESPN when he was arrested for domestic violence and stalking a then-girlfriend. He took a plea bargain that spared him from the possibility of being convicted and sentenced to five years in prison, according to the LA Times.
As the Chronicle put it, "Mariotti was confident that he would be accepted in San Francisco, where accusations of domestic violence — later dropped — against Ross Mirkarimi nearly ousted him from the San Francisco sheriff’s office in 2012."
According to the Chronicle, Mariotti compared the plight of the Examiner to “what I walked into at the Sun-Times. But I was able to keep it alive.”
