(Reuters) - 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.
