Hi everyone I'm Diane Macedo thanks for training with us in today's update police in Louisville have declared a state of emergency ahead of an announcement and the Rihanna Taylor case. 6 officers are now under disciplinary investigation after police shot and killed Taylor in her home in March. Any day now the state attorney general is expected to announce whether some of those officers we'll face criminal charges. Also memorials are growing outside the Supreme Court following the deaths of justice Ruth Bader Ginsburg. Tomorrow her casket will arrive at the supreme court for a private ceremony. Children lie in repose outside the court where the public can pay their respects. And on Friday justice Ginsburg will become the first woman to lie in state at the capitol.

It just at the suave and you put in both nationals for ten seconds each side. And and then you're and then you're done Cornell says it's conducting nearly 50000. Test a week using a method called pooled testing explaining. Hopeful testing works we go and we collect samples from multiple people and we combine them together and run one test. If that comes back negative than we know that all of the people don't have the virus but if it comes up positive and we can go back and test each person individually. Right now the infection rate on campus is well below 1% but it wasn't always that way. Early on they had problems with clusters. They had some parties before we started or.
