California coronavirus cases surge more than 10,000 in single day

California reported more than 10,000 coronavirus cases on Tuesday, a record rise for a single day that also surpassed the number of contact tracers recently trained by the state to detect and prevent potential outbreaks. California is one of several U.S. states that have reported surging numbers of new COVID-19 infections over the past week, raising questions about how U.S. President Donald Trump has handled the crisis and impeding state plans to lift lockdowns. The 10,201 new cases reported on Tuesday took the total number of cases in California since the start of the pandemic to nearly 284,00. In June, California infections more than doubled with over 117,000 new cases.
