Los Angeles pharmaceutical billionaire Patrick Soon-Shiong announced plans to provide University of California regents with a $100-million guaranty underwriting the county's latest proposal to reopen Martin Luther King Jr.-Harbor Hospital by 2012. Soon-Shiong said he has been invited to address regents Nov. 19 during their three-day meeting at UCLA, when they are expected to vote on the King proposal. The hospital closed inpatient services two years ago after inadequate care led to medical errors and deaths.
