Next Tuesday will be a big day for billionaire Ron Burkle. That’s the day he is expected to submit a bid for several Knight Ridder newspapers including the Mercury News and Contra Costa Times as part of a union buyout of the papers. Also Tuesday, a bill (SB 1015) that will keep parts of his divorce records secret is scheduled to be heard by the state Assembly Judiciary Committee, according to a “Legislative Bulletin” from the California Newspaper Publishers Association, or CNPA. The bill’s sponsor, State Sen. Kevin Murray, D-Los Angeles, temporarily put the bill on hold on Tuesday because he didn’t think he had the votes for passage due to scrutiny from newspapers including the LA Times, the Torrance Daily Breeze, Associated Press, Scripps Howard News Service, Vacaville Reporter and Auburn Journal, according to CNPA. Now the CNPA says the bill is alive again and Tuesday’s hearing should be an important one.
