A spokesman for the Chicago-based Tribune Co. declined to comment.
While Keys did not directly address the federal charges Thursday through his voluminous Twitter feed, commentary from his more than 23,500 followers and even a story about the news indictment were retweeted from his account.
He did not address the issue on his Facebook page, where his last posting Thursday was about the best way to make a grilled cheese sandwich.
According to Keys' Facebook profile, he is single, lives in New York City and works at Thomson Reuters Corp.'s New York office, where "I get paid to use Twitter and Facebook at work."
Reuters has been expanding its business in the United States. This year, six of Tribune's seven newspapers dropped The Associated Press for Reuters, citing cost savings. The Los Angeles Times stayed with AP.
